Does it need to be tuned?

Post by spetz »

Hey guys,

I want to take my car to a track event next weekend.
The problem is my tuner as stuffed me around a bit and the car won't be tuned by then.

The MIVEC motor has:
  • - 65mm TB
    - RPW extractors
    - de-cat
    - 2.5" exhaust
    - Ported and polished heads
I have a adjustable FPR and have set the pressure at 42psi (up from stock 38psi) to avoid any leaning out.

My only concern is how the 65mm TB and P&P heads change the AFR.

Does anyone know or have any experience with similar mods?
I have driven the car on the street (to and from mechanics) and it drives fine but that was driving it gently.
