Everything went well until I raced with a friend of mine to see the actual results before and after. Results were identical as the stock tune. Seems that the car didn?t pick up any power after the tune. His car is a copy of mine running on stock tune. Only the throttle response is noticeable. Let me know your feedback and recommendations. Thank you
