I always drive in Sport Mode with my Blitz Throttle Controller set to SP2, I have K&N Intake, Borla Full Exhaust, and Sikky Headers. I enjoy my car and drive pretty aggressive, since I installed the headers, on wide open throttle my car is hitting the rev limiter and making these nasty noises before shifting between 1 & 2 and 2 & 3. I know others must be having this problem, I believe, and I'm no expert, that the ECU is telling the car to shift to late because of how fast my car is gaining rpm's due to the mods, any advice out there as to this nasty noise. Of course its alot worse with the cold dry air, the car sounds like a wicked monster even without hitting the limiter
Thank you for any advice.
