I got an 09 LMM and removed the muffler and tailpipe lastnight no difference in sound. Which is not good. Planning on going with 5" straight pipe from the turbo and EFI Live but having trouble with finding any body around Houston/Pearland that has confidence in tuning my truck. Need assistance if any body has anything.

 

If you're buying Efi there are tons of tuners who can email you a tune. Duramaxtuner, diesel addiction, Idaho rob, moonshine, mcrat. There are tons more.

 

Look up PPE programmers, My brother had one on a 09 CCSB 4x4 duramax, all that was done to it was 5 inch exhuast and programmer and it ran a 13.3 in the quarter.

 

Yeah i was looking at PPE Hot +2 but havent found any feed back or reviews on it.

 

I can do a DSP5 EFILive tune on it around the first Feb. I already have the DSP5 switches instock too. I'm going to an EFILive Diesel tuning class put on by Starlight Diesel to get all the down and dirty diesel tuning secrets next month. I've already tuned a hand full of them and they run pretty good, including my own 07 LBZ Durmax tuning is something I'm going to be getting into pretty big in the next few months.

Oh, and I'm an EFILive dealer as well,

 

DSP5 EFI live i was told the best for my truck by a diesel specialist. Im really interested to see what you learn at the class. is there anything else i need to do to my truck besides the exhaust?

 

A Lift pump really helps if your looking to really up the power.

 

Ive heard of twin CP3's but im not looking to spend that much money.

 

Air Dog II lift pumps are pretty common but a bit pricy at around $600. There are cheaper ways to do it though. i have the Air Dog II on my truck though. Lift pumps are just a inline fuel pump to pump fuel from the tank to the CP3 high pressure pump so it doesn't have to "suck" fuel clear from the tank.

 

Ok thanks for the help and whenever you get back from your class let me know and ill head up to the woodlands and get you to tune my truck.
