    I had the car on the dynojet (Model 248x) and the car produced consistent numbers between 333 and 340rwhp over four pulls. Unfortunately I did not dyno my car before the upgrade but I have been told it should only put out around 310rwhp.

    Definite improvement…car is punchier. I can’t put my finger on it, but the character of the car has definitely changed, for the better. Excellent deal.
