I got a stock h22a obd2, 75 wet shot , with a msd dig6 set at 8k. the shift light had a 7600 pill. at that shift point i hit the rev limiter. is the stock limiter set at 7600? the light is taped into the msd so i dont think its off. the stock tach was at 8k when the light went off. going to try a 7400 pill and see.

 

the stock tach is always off...mine usually reads somewhere around 8k when i'm at around 7300-7400...but that's where i shift usually...my rev limiter is set at 7500 though (tuned that way for motor reliability) so i'd say 7400 is a safe bet...
