i have a cam only car and i wanted to put a 125shot on it, wanted to know what most people are doing as far as the tune? do you let the car make all the timing corrections? or is it better to have a nitrous tune?

Than i would get the motor tune done on the dyno. then take it ot the track to clean it up. After the motor tune is good than you can get the nitrous tune from there. IF you want to be able to adjust it id put something liek the lingenfelter timming tunner on it.

well i have hp tune, so i can take timing out at the track. isent rule of thumb 1/2 a degree for ever 100hp
Rule of thumb is more like pull 2 degrees for every additional 50hp shot.
