hey guys, my buddy has an 04 GMC. we put an Edge Juice w/ attitude on it and it was defective so he sent it back. he doesnt want to fork out the extra $150 for the CS. whats another good chip for the LB7? preferably on the fly.

 

Well you could get a quad adr and thats on the fly, but I use the quad s2 on my 02 lb7 and I really like it, but it's not on the fly. They are both good chips but the best for the dmax's are ppe and the best is efi live. Hope this helps.

 

EFI live with DSP5 there are companies who sell pre-tuned ECM's

well guys, my buddys dad called the place up that sold him the chip, ripped em a new one and they sent him a CS free to replace the Edge that was for an LLY (there mistake) put it in 2 nights ago and everything worked fine. thanks for the input and help, good information to use next time i help a friend with a duramax.

 

Sure, glad we could help.
