i have a strange problem...went to tracks, 1st gear revved up to 8200 no problem, shifted to 2nd, and at 6200 the motor sounded like it hit the rev limiter. what could be the problem? i checked the plugs, https://honda-tech.com/zerothread?id=901402 those are mine, so they look fine. i have them gapped to .030...and they are the bkr7e plugs that everyone recommends...my setup is a stock b16a, running 9psi, with the safc hack. what do you guys think could be the problem?

do you actually know what your A/F ratio is? may be a super rich spot in your tuning?
