Head Porting Recomendation?

I believe that some of their work comes from customers that have hundreds of hours on the bench/dyno and have them replicate their findings. Just being around all that performance/technology gave me half a chubb...:D.

They're cnc program for the Performer RPm is not theirs. They bought it from an outside porter. Not the first CNC business i've called that has told me the same thing.
