Nitrous Tuning

I don't recall the exact degrees atc the compression pressure peaks at, somewhere between 1 and something. the more compression your motor has the more timing you have to remove to keep the pressure peak the same. say a 14-1 motor has to remove say 8 degrees for an 250 hit but a 8-1 motor may not need any timing removed. plug reading is your best bet on figuring that out.
