Which chip is recommended for fuel milage on a 2008 HD3500 Duramax truck? There are so many out there and was curious as to which you should and shouldnt buy?

Try Diablo Predator.

PPE will prolly yeild the best, but the price is alot more. I would quadzilla stealth 2. I have had all 3 (including predator) and liked the quad the most. Quad got better MPG than the predator for sure and the PPE was hardly more than the quad. Quad has alot of power down low and seems alot stronger. PPE snd predator seem weak down low.

Im pretty sure that the predator tuner doesnt mess with your warranty as long as you take it to the dealership and have it put on. I know three guys who have the predator tuner on a LB7 and two LLY's and they dont have any complaints.

Rip out all of your dpf emissions crap and get a efi live tune, that will help out your mpg a ton.

lope tunes blow Its cool until the first red light you sit through in that surging POS. I do plan on putting one my DSP5 that way if I get pulled over for smoke hit the switch. And "Sorry officer there is something wrong with my truck. I'm on my way to the dealer."

For the LMM, the best thing you can do for mileage is get rid of the DPF, a believe Quadzilla, PPE and a few other handhelds will have a DPF delete mode, of course you can have tuned with EFI live and get the best of the best, My uncle and a few other guys I know have LMM's with the DPF deleted and the mileage/power gains were unreal. Just deleting the DPF and a small 60-70hp tune will be a huge gain in MPG's
