My cousin finally got a wideband on his truck, it doesnt have any major mods other than shorty headers,exhaust,cai. I told him long ago not to descreen the maf but he did it anyways. Well with the current tune it had after the wideband was installed (plx btw) it was reading 13.2. Well like ive done in the past I tweak the maf calibration table if it was close without altering it too much, but this is having no affect at all and im kinda stumped and I think it could possibly be his maf since he descreened it? I think I have a log I can post up tommarow after I get it from my laptop,but I was mainly asking if a altered maf would cause problems like this?
Thanks
