Need help Porting..
I am running a 52mm TB with a stock LT4 intake. The rest of the car is modded but I was wondering how much of a difference running a 58mm Tb with a ported intake?
Also I am looking for the correct fuel pressure. I have the stock injectors with a fuel pressure regulator and I am looking at about 28psi.. You can loook at my signature to see my specs.. The car is very modified without being a 383.. All top end.. I am running in the 12's now but would like to get into to 11's..

Your fuel pressure should be about 42psi or so. Raising your pressure up is probably going to make a pretty big difference in the way your car feels, unless it was tuned down for some reason?

yea your pressure is low! you probally want to get lt1 edit!
that would help alot and could possibly bring you into 11's
if not...r u running slicks? try that!
then what I would say is go to 3.73 rear
