Mr. P: I really haven't figured out what system. I currently have an old Accel/DFI system on the car. I really don't have the tuning expertise to get it running the best. I want a pro turner for this new motor. I'd like to know if someone in my area was a crack tuner then i'd go with the system he was familiar. I'm in St Louis, MO.

Should I go with the 4500 size and put a tapper under her?
