Mine is a zetec manual tranny with race header, SRI, ported TB, and 2.25 exhaust.
I'm not talking about programmable features like red line adjustment or tire size but things that improve power or driveability.
I have Tom's tune and I was really impressed with how it woke up my zetec. It shifts alot firmer and runs cooler and over all I gained alot of power I don't know how much but it's alot faster. Between 2-3 it pulls really hard I was like wow this is a 4 cylinder? I bet I could keep up with a older stock 5.0. Thanks Tom
