Hi guys recently new to this forum and to a duramax. Love the trucks. I am looking to delete and tune my truck (2007.5 chevy 2500). Egr delete and dpf are both on the way. So that leaves getting it tuned. A guy here locally told me he would put efi live with a 5 position switch on it for $575. Not trying to build a race truck just more efficient and some extra power when needed, but safe for stock transmission. Does $575 sound fair. (Not sure what tunes he uses)
