Re: Suggestions for a power programmer
Thanx! I figured I would ask the question in the "technical and performance" side of the forum, thinking maybe I'll get more info. Thanx. Do you use 93 octane? The only reason I ask is my mechanic which is a hummer mech said to only use 87 octane. I don't know why, maybe because stock tune? I know the programmer changes all that and will ask if you want to use regular or premium. Your thoughts? What do you think or know about hypertech?
Thanx, Eddie
