Need help tuning!
I just bought a fuel pressure reg. I just need some pointers on what the best way would be to tune the car. My car is a 305 tuned port injection and it has stock injectors. So any help is needed.

Well, hopefully you bought a fuel pressure gauge when you got the regulator.
Depending on mods you should set the fuel pressure at 43 with the vacuum hose off and plugged. The best way to get optimum setting is to go to the track and increase pressure 1 psi every run until the car slows down then back it off 2 psi.
