I am soon to be sporting a stage 3 block from Axis which is capable of 8000+rpms. I will also have some larger duration cams, probably 272I 264E or 272E I haven't made up my mind. It is my understanding that you don't tune for cams, that you can slap them in and they work. Is that true or not? If you do have to tune for cams will street tuner have the appropriate parameters to tune for cams?
