- Stock displacment LS2
- 231/239 .644/.651 115+3 Cam
- TFS 220cc Heads
- LT's / 3" Catback
- TVS1900
The bypass valve on the TVS1900 is open at all times, so the car is N/A until ~100kpa when the bypass valve closes and boost comes in.
Is there any reason that my high octane timing table should be modified when NOT at wide open throttle? I'm not sure if the cam will have any effect there or not.
