So you think setting it at 38 and locking it would be good or is it the same either way. I will be shooting a 150 shot through the throttle body thats why i was thinking of spout out and locking, so i can take timing out easier, because don't you take timing out from the total and not the base idle when setting it up for nitrous. I no it's 2 degrees for every 50shot.I have it set at 16 now and at the base idle and when i bring revs up to 3000 the total is right around 36 /38 what you think
