Car is SUPER rich and I'm not sure why

[GSXV8Killa]

Finally got my car all together and on the road but now Im having what seems to be a fuel issue. Stock injectors and boost. Have to slowly roll into the throttle because car sputters and wont clean out then when it does just doing a pull at 1/2 throttle the wideband is reading 10.5-10.8. Im new to all this but i feel like its leaning out? Also once i get over 5-5.5k its hitting what i believe is fuel cut. My fpr is set at 43-43.5 and I am running a walbro 255

Check your spark plug gap. Should be about .028 if I remember right. I had a sputter problem and that was the cause. Also it might be a boost leak.

If your wb is showing i n the 10's, you are pig rich. You are loosing metered air some where or your fuel pressure is set too high.

While letting the car idle last night (which is high around 1400) the wideband was reading anywhere from 11.0-12.8. Then it was staying in the 12.5-12.7 range then jumped all the way to 10.9. This is all at idle without touching anything. I turned the fpr up and down without making a single difference in the readings.

Are you on the stock 2g MAF?

 

[GSXV8Killa]

Yes and I just recently cleaned it

Could my MAF be bad and giving false readings to the ecu? I have a MAF translator setup in a box somewhere. Should I throw that setup in and adjust the settings for injector size and see if the car runs any different?
