Edge doesn't appear to make a product for this powertrain yet.

Does anyone else make one?

www.pacificp.com Try them, Pacific Performance is about the best out there for the d-max, they know how to make some insane power.

PPE is one of the one of the top tuners out for the LBZ just remember there #s are at the flywheel not the wheels and they generally have very high EGTs. A few post down I just posted the Predator is out which has always been a solid tuner. And is rated at 120hp IIRC the PPE is 200hp so they are about equal at the rear wheels. Bully Dog, The Duramaxmizer, and I think there is one more but I can't think of it. If you have the LBZ you better only run a tuner on the lowest setting the stock power is all ready straining the tranny and don't be at WOT in the 5th and 6th up shifts. The Edge is supposed to be out in the fall whether that is this year or next we don't know.

Yeah, I read were the Allison 6spd is already at it's limit with the LBZ. That sucks.

There are a few guy pushing, I haven't heard of anyone limping one yet. I'm thinking of a 40hp tune mostly to remove the speed limiter, but don't really want to do the tranny yet.

you would think that GM, or Allison would realize that a large portion of the people buying these new diesels will turn them up, so why can't they just make the stuff stronger from the factory?

Most people keep them fairly stock, but it isn't like GM doesn't put TQ management on everything it makes anyways.

the biggest complaint on the DM 6.6 is fuel economy.. got plenty
of power.. just want a better MPG... getting the torque
improvement does increase the economy, but overfueling for
the hp is the clincher... usually a 60hp 150tq is fine for
economy and not straining the trans. its the 10000lb that
kills and no monitoring.

Well they tested the big 3 and the Dmax got the best mileage, and a 60 hp tune could put a LBZ into limp mode.

no offence, but do you think that GM even cares or takes that into consideration?? It is not their responsibility to take into account that the owner might make aftermarket changes. They designed the drivetrain to be strong enough for use in original factory configuration. How can you blame GM or any car company for "not making things strong enough when the owner mods the vehicle"?. I ran 52 psi of boost on a stock LLY turbo for a month and guess what, it blew up. It would be ludicrous for me to go off on a rant blaming GM that it blew up. They designed it to run reliably at 24 psi. I exceeded that, so I paid the price. No one is to blame but myself. :)

It is not the hard parts in the Allison that are failing. The clutches simply slip. The hard parts are stronger than pretty much anything else out there in the light-medium duty market. The LCT1000 is physically identical to the Allison 2000/2400, except the gear ratios in the 2000/2400 are different. The 2000/2400 is in pretty much every medium duty truck, school bus (old school busses used 545's), transit busses, etc... The input shaft is about the size of my arm.

just my oppinion..

Plus, the factory wouldn't be able to justify the cost of strengthening any further unless they produced higher-output vehicles off the showroom floor that demanded it.

Why would anybody want something built to the limit from the factory? It'd be great, but anybody could buy the exact same truck & yours would be just another one in the pack. The fact that they're made the way they are leaving plenty of room for the aftermarket to improve means you end up w/ a truck you can customize to be uniquely yours.

That, and there are those kooks out there that prefer mediocrity... Any auto manufacturer's goal is to find a happy median

Amen to that, I will be holding on to my truck for quite some time. And I expect the Edge would be out by fall, I lucked out and was picked as part of the beta testing so I happen to have one in my truck now. I don't have anything to compare it too, but I will be sticking with this for my programmer.

Is it actually the Juice module w/ the Attitude monitor? I had heard a few months back that Edge was looking at releasing the Evolution programmer for that, only it would be like the tuner they make for the F150; looks like (and has the same functions) of an Attitude monitor, but it plugs into the ALDL and uploads a program like a tuner. It stays plugged in 100% of the time, and will change programs on-the-fly, so as far as the driver's concerned, it is no different. Just curious...

smokinjoez
09-11-2006, 11:49 AM
It is the Juice with the Attitude. There are 5 programs that come with it and a sixth "hot" program that can be unlocked to give an additional level. The programmer basically is permanently plugged in under the hood with the Attitude being in the cab. You can adjust on the fly and it also monitors about 14 different parameters. You can view 4 at one time. So far, I love this thing, but I have never had a programmer on a diesel before. My hypertech for my '03 1500HD was a pooch, I couldn't tell the difference, but this thing...there is no doubt something is going on. As for the uploading a program, I don't think it does that. My understanding is it alters the signals before they get to the ecm. I really like that because you can take it out and be completely stock without worrying about something going goofy during a rewrite and completely screwing up the ecm.

I had heard rumors of them maybe trying something else for the LBZ, so apparently they decided to stick w/ this. Good call on their part IMO.

They're always off on releases - think "A2" monitor, or better yet think about the wireless back-up camera that was supposed to be out w/ it and still hasn't been released. Not strictly a bad thing since more R&D means more solid product, but earlier this year they were talking a late June release for the 06 LLY/LBZ Juice. I'm wondering if it'll also work for early 07 too...

Sounds like Edge is getting a little gun-shy & playing the safe route w/ their power levels... Then again, it's not suprising that they'd make some changes now that they're owned by a gas-burner performance company...

As long as it’s an LBZ yes, but for the LMM all bets are off. It shouldn't take to long for them to release something if they decide to, it took them a while to crack the LBZ new ECM.

LMM will have the same physical Bosch E35 ECM as the LBZ so figuring out the LMM shouldnt be too hard I dont think...

The Edge is either underrated or I heard wrong, because a member dyno'd his LBZ with the Edge and it did well assuming the Edge don't do anything on 0.
Lvl - Hp - Tq
0 - 285 - 488
4 - 382 - 670

There is a company called TSPerformance that makes an MP-8 for the duramax that is adjustable up to 100HP at the rear tires. You can adjust it when driving to suit your driving needs. It can also increase the fuel milliage by 2-3 mpg over stock. Its available for the LB7, LLY, LBZ.

I talked to a guy at banks engineering and he told me that there was no problem cracking the ecm but rather GM upped the fuel pressure on the stock LBZ and so they had to go back to school on how to adjust the fuel curves and not damage the engine. He also told me they had no problem with being the last one to have a programmer out because theirs would be perfectly safe.

What did you expect him to say? He's trying to sell you something. I would ask people who use the products, not someone who sells them. Big difference.

Funny how programming has been the issue for everybody else... Sounds to me like they're still dialing in their programming and haven't started on-vehicle testing. Really its irrelevant since its not available & won't be for a while, regardless of the reason.

Nothing wrong w/ asking a sales rep provided they're honest - they're there to answer your questions. Call some other companies & ask them the same questions to see what lines up & what doesn't. Then post it all so we can call bvll$h!+

I alredy got tired of waiting for banks to get their s**t together and am running with a pacific performance programmer. I wanted banks because some of my buddies have had great luck with them but another friend of mine has the same programmer I ended up buying and has had no problems. Also I'm still waiting for banks to come out with the boost gauge they have been telling me should be out in 6 weeks but its been almost a year.

This is my first turboed vehicle that doesn't have a boost gauge preinstalled factory so I'm looking for ease of installation seeing as I don't know much about turbo plumbing or where it would plug in. I only know what I read and hear from others. If you have any suggestions let me know.

That's pretty much a Banks standard - if they don't have something but feel there's some inkling that they may in the foreseeable future, they'll tell you 6 weeks - that's how you know not to hold your breath. Actually, I wouldn't hold my breath unless they've physically released the thing.

Also had to change the egr valve.

Why?

The only trouble I've had out of my truck (06 LLY with the power pup, afe intake, and exhaust) is an occasional trouble code that comes up when I'm towing. If my memory serves me correctly, the code is P0104 and I think it was something about recirculated air at some location. I didn't notice any performance loss and it goes away after I quit towing. Has anybody else run into this?

who would buy a truck with a tranny that can withstand 2000 lb/ft of torque with and engine that puts out 600 from the factory, if they can buy one that can withstand 700 lb/ft of torque for 2000 dollars less? It does not make financial sence for General motors, or any other company to overbuild their vehicles just for the sake of the customer to put aftermarket products on them.
Do not get me wrong I love to modify anything I can get my hands on but if engine modifications are in the foreground then you must also look at everything after the engine ( trans, torque convertor, driveshaft, and rear axle), gone are the days fo over engineering an vehicle. What the big 3 looks at now is getting the vehicle bast the warrenty period and then it is the owner's baby. As sad as that might be it is the truth....

LostBoy
10-23-2006, 09:02 AM
I think most people would buy a truck that can hold 3x the torque for only 2K - relatively small investment for the gain. Wouldn't make sense for the OEM to build them to hold more power than they sell them with, though.
