tuning or not ??

[str8stangracer]

i have a 75mm tb, gt40 manifold, fpr @ 45psi, planning on installing the trackheat f series cam and a 76mass with 30lb injectors. after installing the calibrated mass and injectors will i have to tune the car? or will it run after the cam and mass installed? the only thing i will do after installing is disconnect the battery for a while and reconnect, then turn the car on and leave it on idle for a good 10 minutes just in case. will that be good enough?

mine runs fine (check out my sig) I'm sure that a tune would help but far as running ok it should.

Why do you run 45 psi? I have a 347 w/75mm TB, 24 lbers, ported Cobra intake, etc and I currently run 39 psi. Should I raise my FP? Anyone have any recommendations? Should I get some 30s?

You guys need to start putting your combo's in your sigs, so people know exactly what you have.

Heads here are the determining factor.

If you know your car well, add or remove fuel based on how the cars feel.

Regarding my question, I have TFS TW heads. Sorry about that.
