I'm just past week 1 of my stage 2 tune with required supporting mods. I went with stratified's tune. I tried the cobb OTS tune and while it was fun, i prefer the stratified tune. The difference from stock to stage 1, to stage 2 is incremental but noticeable. I don't know how my car would stack up against my car stock from a drag race, but mid gear in my stage 2 feels miles quicker. The fiesta is an oddly positioned car. Its quick enough for people to want to make quicker, but not really expandable enough to be a real platform for straight line racing. Then again, that's not the purpose of this car.
