What does it fill like or what happens when the mass air flow sensor goes out. Does it start leaning the engine out? Thanks guys lator

most of the time (MOST) it will throw a code. it could go either way. take it out and clean it. find a log tool and have someone or yourself looik at it. is the screen it it or gone.

 

I did take the screen out of it but it seems that my truck has leaned out a little bit and doesn't have the throttle respone. I called allen and he's sending me a new tune out so maybe that will fix it.

Thanks

Usually you'll bog down from any throttle input above idle and throw a code as 02Denali said.

Being as you have a blower, without a MAF wouldnt the PCM rely on the VE table entirely for fueling which would mean BOOM as soon as you hit boost??...
That wasnt phrased correctly, but that is a question based on what Ive been reading...
