im still up in the air and unsure as to if i need to upgrade my fuel system along with the mods im puting on in the end of june. i am putting a exhuast manifold, 02 housing, down pipe, straight pipe, catback exhuast, intake, fmic upgrade, fmic upper and lower hard pipping, boost controller and all the appropriate gaskets, bushings and gauges. im unsure if i need to upgrade my fuel pump, injectors and/or get a fpr. this is going to be it for mods for me. im not looking to go insanely fast i just want to be close to 300awhp on 93oct pump gas. if you have any suggestions let me know but my primary concern is fuel delivery with all the added air thats going to be comming through my engine.

edit: im going to have the boost set to 22 psi.

 

just get the pump, do your tune and see what your a/f is. At that time, then decide if you need injectimicators or not

 

I would get the pump and 660's

 

For 300 whp the stock pump is fine. Look at the flow rates;
A 190 pump at 12.5 volts is known to support 350 whp. When you take into account our relay circuit/additional voltage, our stock pump out flows it.

The stock fuel system is not the weak link in making 300 whp. It's tuning.

 

cool, thanks for all the replies. it seems as if tuning is the major player here. good thing tt is only 30 minutes away from me! i should probably make an apt. soon. again, thanks for all the replies.
