With the new injectors in it , I had the map re-graphed and put in a new bigger wide-band oxygen sensor and a bigger fuel pump maxing out at 55psi. After my last dyno tune run 2 days ago the pump was maxing out and caused the engine to lean out. Placed a bigger Bosch fuel pump and now my Air/fuel is at 11.8 @ 7900RPM.

The only thing I don't like is that the pump is now noisier.

Is 11.8 AFR running within recommended ratios.

I'm having my first full dyno run tommorrow, so I'll keep you posted on it's performance and RWHP.

Good to hear. 11.8 is maybe a tad rich but better safe than sorry.
