Chrome user having major issues and out of ideas!

The tuned ROM from 3sx shows they did everything they could to lean it out. Now that the narrowband are setup properly this tuned ROM should show a change. That's why I want you to flash it.

You know .9 volts on the narrowband is rich and .1v is lean right? 12.5 on the wideband is rich. Lower numbers on the wideband are rich. Higher numbers on the narrowbands are rich.

All the logs you've sent and even in that screen shot indicate a rich condition.

Yes, I know it is running rich, what I am saying is that when I give partial, moderate, heavy throttle the car goes completely lean (verifying on wideband) and the car feels like its running on 3 cyclinders. after a second or two it will snap out of it and go into boost

Honestly I am starting to loose track of what I have done. what are you wanting me to flash to it?

Oh okay. That's something different entirely. We can play with the accel tables to try and tune that out but honestly, if the car has no mechanical or electrical issues, the stock settings work perfectly.

Where are you sourcing the vacuum for the fuel pressure regulator? Can you verify the pump is getting full power? Are you running an open atmosphere BOV?

The rom you emailed me with the closed loop settings set back to stock.

already did that.....no change

[twinspoolin94]

BOV is recirculated, pump is getting good power (its hotwired) checked it in actuator mask turns on and off no problem, its also new. fpr is sourced of plenum nipple only

It still ran rich at idle and lean on acell?

I've seen botched hotwired pumps make the car run like ass. In fact, one time I had to diagnos it on the side of the road...

You talking the nipple in the back side of the plenum? Is it pinched?

[twinspoolin94]

Yes same condition.....like I changed nothing
