hey there im a newbie but i just bought a 2001 lb7 duramax and its completely stock with 121k miles on it and 10" of lift and 37" tires
. anyways i was wondering what is the best chip for it. i would like for it to be able to smoke and have a nice power gain without messing up the truck or hurting the tranny.i've heard of smoke switches but have no clue about them. also efi live is a little to pricey and advanced for me but all ideas are greatly appreciated.also been hearing about ppe,edge,smarty,and banks six gun.thats just a few programmers people have told me about.thanks
