Hey guys my cousin bought a 24V not shure of the year I think a 00. Right now its stock with an exh brake to hes not happy with it yet he cant even keep up with me or pull me backwards yet. First off we are probably ordering a 5" turbo back and building a new intake this weekend so she can breath. Then some guages. My question it whats the best chip or tuner for the 24V. I remember having a bully dog on my truck that was a joke then I got a custom chip from DP-tuner and its was like night and day. I dont want him to go through all that so help us out. Thanks.
