yup, its basically a back pressure issue. I have the .86 AR housings, berk test pipes and AAM 2.5" exhaust. I'm going to see what we can do with tuning before upgrading the exhaust though.

I'm running bosch EV-14 650cc injectors right now, but I have a set of DW 850cc going in soon.

Rougly a couple of months is not bad at all. Man I'd love to ship my car over there to have them build it up someday

probably a good idea, but I'd be curious to see how far a hardwired aeromotive 340 pump would go before running out up top.

I think the issue is the 650cc injectors. Not the pump or the lack of a return system. I am on the same 650cc injectors and they were close to maxing out at 530ish rwhp. Wonder what the result would be with the 255lph and say 850cc injectors.

its possible its related but FI ran into the same issue around 550whp, they had to compensate by adding more fuel up top
