well i thaught i would cover all my bases first now im stumped, truck hits around 25, 26 lbs of boost and its like it defuels or ? fuel press is 12 ish at wot and cleaned map sensor that was clean anyway, i did find corrosion on the ez connections at the map sensor, cleaned it and still the same. any ideas, the iat should be next to map but there is jst a plug and no harness so im not sure about that, oh yah no codeseither

 

what injectors do you have? fill out your sig so we know about your truck.....

stock inj as far as i know

 

what does it do after it defuels? e.g. cut out,drop rpms,shake,(burn tires off j/k)

 

i wish it would burn the tires at a roll, no its like it hits 20 ish lbs of boost and just like it drops the boost and goes to 0 then builds right back to 20ish lbs of boost then does this over and over egt is relavent to the load at the time 8 to 1200 ish

 

maybe throttle position sensor?
