Ok i have got gt-40p heads, tf stage 1 cam, 1.7 rockers,fm headers,h-pipe,flows,pullies,73maf,70mmtb,cold air intake, stock injectors. So do you guys think that the stock intake manifold is causeing my engine to choke at like 4600. after that there is no power. And what bout the injectors. is 19 to small for this setup. I was told the stock intake is why my car is running rich at wot. Just curious. Cant get a intake for a while even if it is to small but just wanted to know for sure. O the intake is ported for the 70 mm at the opening so there isnt a lip there but that is it. thnx

Just curious, are you running w/ mass air conversion or speed density?

You might wanna look at porting what you've got the rest of the way, otherwise I'd say an intake would def be your next step. I'd get that before injectors but those would be a good idea once you do get an intake. Don't know how much porting is though so that's up to you.

I didn't notice the injectors before, but I agree with VertStangGT86 about the stock intake being your bottleneck.
