codylbz 10-18-2009, 04:43 PM I have an '07 GMC 2500 Classic CC. I am wanting to buy a preprogrammed ECM from someone so I can block the EGR and install an exhaust and not get any codes. I am not looking for much of a power increase, mostly just mileage. I need a tune that is safe for the transmission and one that I can run without an EGT gauge without any worry of it getting hot. Who do you guys recommend I go with? Thanks Cody maine dmax 10-18-2009, 06:25 PM Try IdahoRob, he has done alot of tuning for people on this site and someone I know locally. Tanc Crusher 10-18-2009, 06:44 PM Nick can help you out too. While at it get a DSP5 tune and switch so you have 5 tunes and switch on the fly. EFILive just released this feature for Bosch ECMs. Just had Nick do my LMM. Working great.
