Hey Guys I was wondering if you could help me out with tuning my new combo. I have a 347 with TFS twisted wedge heads, TFS Stage1 Cam. 30lbs injectors, 75mm Bullet MAF, tfs trackheat intake and a FMS 65mm t-body and a bbk 190lph fuel pump.Can you guys suggest fuel pressure and Timing.

You generally want to leave your fuel pressure at 38-40 psi with the engine running and the vacuum line removed from the regulator. You can set it higher, but the computer will learn and trim the pulse width anyway.

For timing go with 15 degrees of initial advance. That would get you in the ball park. Tuning a car to just run decent is the same basics as tuning a relatively stock car. Now getting the best nubers out of it is a different game all together.
