I did tell him what gap I run. But my main point was to tell him it is the box rev limiter that is the issue, no question about it. If he adjusts it way up, the car will respond. On my car, on the chassis dyno, the HP picked up 41 at 5800 with just the rev limit change only. The only other change to the car was to dial up my fuel pressure from 10 to 11. The car picked up 6 MPH in the 1/4.
