Like HDsouthcali stated, you are wasting your money, just get all your mods together, hold a gtg to install them and then get a dyno custom tune. I also ran the pre-canned tune(what come with the predator) 91 octane for about 6 months then I got a custom dyno. I need an updated one due to other mods I have done to my truck and what to see what she puts down.
Every truck reacts different to each mod.
