Theres a few real, professional, "tuners" (ahem^^^^^) that might take offense to your comment "Looking for some more power without having to spend the weekend tuning". You don't have the tools to do that. No... you do not. And it took the pro's much, much, more time than that (and some very expensive tools) to get more power from that engine.
If you think a universal sensor faker, and a gallon of "race fuel" makes more power, you have a lot to learn my friend
.
FYI, race gas is good. It's better quality than pump gas, but it won't ever make more power by itself because it has the same BTU's as pump gas. Oversimplified, the higher the octane rating the
slower it burns, resisting detonation, allowing timing to be advanced. Without proper tuning, buying high-octane gas is just wasting money. It does smell really good though:)
