It made the car more tractable at moderate speeds, a bit easier to drive, less shifting required. I do not have my foot calibrated yet with stepping on it with authority. Uh....I am currently prone to accidental wheelspin.
274 (?) whp, 250 something lb feet of torque. Precisely on target.
10 lbs boost. Stock ignition settings.
Instantaneous, no-lag, right-now power and plenty of it. More than enough.
I absolutely love it and it seems like it tied all my other performance mods together to form a singular piece.
