Ok I have a 2004 chevy 3500 duramax lb7 it's bone stock and I'm looking to put a 5 inch turbo back exhaust and aftermarket air intake to make it breath better also I'm wanting to put a aftermarket lift pump on it to keep strain off the injectors and the cp3 (injection pump) my question is I've been looking at the fass fuel systems should I go with a 95 gph or a 150 gph (gallons per hour) ? And what brand does people recommend ??? I might in the future put a tuner on it but I really don't want to I just want a cts screen to be able to run diagnostics on the injectors and stuff
