losing power

need help!! when i'm at wide open throttle, i pick up good speed and my turbo psi is at about 15psi , running in the blue (rich)on my a/f gauge, but my speed bottoms at 75mph when i hit 4th gear at WOT, good boost, running rich. i am runing 20+ injectors with static fuel pressure at 32psi. will not go any faster!!! appreciate all the feedback.

No matter what your A/F says +20's at 32 psi pressure static is WAY too low for 15 psi of boost.

How is the car acting?? stuttering, or just flat?? How does 3rd gear act?? Will it go past 75 without issue??

when i get to 4th its just flat no sputtering. increases speed good all through 3rd gear but when i hit 4th it flattens out. in highway driving it drives really great and i can go way over 75mph. it seems to happen only on WOT.

Up the Fuel pressure to 45 psi static. Try it again...

My guess is the car is pulling all the timing due to an EXTREEMLY LEAN condition.
