Either way. Air to file mixture needs to b precise. Mine is set at 14.2. But don't go by me. I'm a little involved and have a high fuel mixture due to bigger injectors and massive air induction.

My Evolution manual says the level 2 or tow tune is 87, the level 3 or performance tune is 91.

Mine don't. Lol. I can't even run 87. (And the professor will beat me for this) but if I run 87. It pings bad and runs like a dog. 91 or better fer me. But if your manual says that. Than that's what u do

Tuner really help in shift points. I have an SCT X3 on my F-150 with a manual trans and I cant tell the difference between stock and 93 performance tune.

What's the sct x3 and in your opinion is it better than the evolution
