I dont understand it...I recently adjusted my FPR i did the all the way in thing and the two complete turns out thing...and then I turned it in about 3/4 of a full turn.....and still at WOT 7psi in 4th around 4k RPM my cars running like 1610F...?

How far about do you all have the needle turned in ??

Either your fuel pump or fuel injectors, or a combination therefo, have reached their full potential as far as fuel delivery.

Using race fuel would allow you to run that level of boost. You can also check your fuel pump wiring. Going with a higher guage fuel pump rewire may deilver a bit voltage to the pump and in turn more fuel.
