My friend advanced my timing think that could be it

maybe ur tachometer is just incorrect. Could be a few different problems.

sometimes when it's cold or at idle, the car will only rev up to 6500, run it and it should go pass 6500.

even when the car is at operating temp it still wont go pass 6500 I think 92 ls have different redline then 90's
