Hello guys I need some help. I bought new a Science of speed supercharger stage 1 and having some issues. Info on kit 50psi on fuel pressure regulator(static), and 7psi of boost.Everything else is stock. (Mustange dynoed at 270whp)

-Issues
-From 1000rpm to ~3500rpm its bogging (only wide open throttle)
-Idle AFR is 16.6 to 15.8 (seems Lean)
-Wide open throttle at low rpm in the bogging zone APR is 10 to 10.5 (seems rich)

I'm wondering that the fuel pressure is to high? I'm lost please anything would help.
Thank you

 

Have you tried contacting SOS ?

 

Where does your VTEC engage?

The reason why I ask is because the FVM that came with my base kit was bad. VTEC was engaging at stock point instead of 4500 or so, and I recall it being extremely lean. Perhaps your FVM is also bad.

 

I seem to be switching over at 5000rpm. I have to go for another ride and see again.

 

Any other mods aside from the SOS kit?
