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.
 
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.
 
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?
