    Re: Top 10 Duramax mods

    depends how much you are looking to spend. If you are looking at some serious power adders, I would recommend a sun-coast tranny. If you can't afford that, then at least go shift kit and torque converter. That will make that Allison bullet-proof

    Re: Top 10 Duramax mods

    the FASS 150 is a fuel pump. It stands for Fuel Air Separation System. IMO the 150 is a little large unless you are looking at a truck that's gunna be at the drag strip a lot. For a street truck, I would recommend the FASS 95. It still helps out a lot when adding a programmer and injectors while being more mpg friendly.

    In terms of injectors, I would run a set of 50hp injectors either from Industrial Injection or ATS. Similar to with the fuel pump, more isn't always better. I have seen trucks make more horsepower with a 90hp or even a 50hp injector than a 120hp injector just because the 120 adds too much fuel.

    I have seen trucks with RPB intakes before, and while they are nice, they are very expensive (as is anything with the RBP logo). I really like the AFE stage II intake as well as the Banks Ram-Air intake.

    The stock 6.6l does have a turbo, but the actual turbo changes depending on the model of the engine. the lbz (and i believe possibly the few 06 lly's) have a variable geometry turbo, where as the lb7 (and i believe 04.5-05 lly's) do not. The lbz also has a lower compression ratio, which actually often means more power with diesels and the lbz comes with a 6-speed tranny instead of the 5-speed.

    I prefer EFILive over Banks because of the customization that the tune has. The Banks chip is nice, but it is rather expensive and you only get the 7th level if you purchase the six-gun + pda. I do like the look of the Banks gauges, but you might also want to look at Auto Meter, just incase you are looking for a different style gauge face.

    Re: Top 10 Duramax mods

    There is a good list that has been posted before. The stock intake is good enough for a truck that still has the stock turbo. Stock injector have been pushed to 700HP. No point in doing a Trango shift kit in anything but the 06+. For the earlier ones you have to drop the trans and if your going to that might as well just have it fully built.
    A new down pipe should be added to the list its better then a new exhaust and only $200.

    Re: Top 10 Duramax mods

    Agreed with the uprgaded IFS. Control arms, ball joints, and tie rods should all be upgraded, especially if you spend a good amount of time in 4wd. If you are doing an exhaust, CHANGE THE DOWN PIPE!

    I hope this helps you some more. If you need any help with any more parts (specifics, part numbers, etc.) feel free to pm me at any time.

    Re: Top 10 Duramax mods

    If your not going to fully build your tranny, go with a banks six gun. I think banks is the best programmer for a truck without a built tranny. It adds the most power and has safety features built in that will prevent you from blowing your expensive allison. If your willing to drop 4 grand for a built tranny, then by all means efi live is the way to go.

    Re: Top 10 Duramax mods

    I agree that the Banks six-gun is a great chip, but it is over priced and does not offer the customization that the EFILive tune does. If you can find a great deal on one go for it, but if you like seeing black smoke pumping out this isn't the chip for you.

    Re: Top 10 Duramax mods

    I think you will be just fine. With a shift kit and tq, you greatly increase the amount of power your tranny can hold without failure. Another thing I would add to the is a TCU. as I said before, ATS isn't my favorite company, but I love how their co-pilot works with the Allison.

    Re: Top 10 Duramax mods

    If you can find a great deal on one go for it, but if you like seeing black smoke pumping out this isn't the chip for you.
    Sorry, but I could not disagree more. The Banks 6 Gun will not in any way shape or form pump out black smoke. Aint happening. I have a 6 gun PDA, and if you pound this thing in level 5/6...it will not allow you to overfuel...that is the main SAFETY feature of the Banks system. If it senses over fueling..it'll shut ya down rather than blow your motor/limp your tranny.

    I'm not in any way knocking EFI Live. That is software that is a whole world away from canned programmers...by a light year or so. But you had better know what the hell you are doing with that, or better yet have someon like IdahoRob or someone that is very higly experienced to do a cpl of tunes for you.

    As far as intakes are concerned..dont bother unless you are building a motor that will get you over 550 Rear Wheel HP. It will not make any difference below that level. As per Dozer, if you get an LB7 or LLY, don't bother with a full Transgo, jsut build a tranny...if you get a later model 06/07 classic LBZ, then by all means get a transgo Jr. cheap insurance for up to about 500+ HP. I too like the extra protection of an additional fuel filter. Bad fuel is no fun at all.

    Lift pump ala FASS 95 or stand alone lift pump (PPE), or an Airdog would not hurt.

    bout all i can add here.

    We are actually in agreement on this. We both said that the Banks chip will not blow out smoke.

    Re: Top 10 Duramax mods

    I wouldn't go with a BANKS TC, just avoid banks, he's too expensive and the TQ is the exact thing everyone sells.

    Suncoast is where its at....theres suncoast trannies in some of the TOP HP/TQ duramaxes.

    Re: Top 10 Duramax mods

    Okay so i checked out the Suncoast TQ's and they got 5-series?? The 1054/1055/1056/1057/1058, so with the EFI live, AEM brute HD intake, turbo-Back exhaust, aFe Intercooler tube, fass 95 and like 50hp injectors, a mag hytec trans pan and the Transgo shift kit and suncoast trans cooler which TQ would best suit the duramax 1054/1058-series?? and is this a good set-up for power and durability??

    Re: Top 10 Duramax mods

    You need to ask them.

    the series numbers is the tightness before it locks up. with a stock turbo and a good tune i'd say go tight as possible maybe one stage looser.

    The loose converters are for the guys that have to spool up a big turbo(s), loose/tight = stall speed (loose is higher speed, tight is lower stall)

    Email them or call them and ask,

    The setup you just listed is a good setup for cool egt's (safe power). Honestly though i'd hold off on the injectors because they're just not necessary unless you want like 550hp+ from what i hear.

    And the transgo kit is only if you get an 06+ LBZ with the 6spd auto.
