Im going to be being a wideband really soon. Either an lm-1 or an dynojet. Run down of the problem: I have a predator with a mail order tune. For some reason im dynoing the same power as stock because im running so rich. Ive talked to my tuner(sambandit) and hes been over my tune several times(its not that complicated) and he cant see anything wrong. I have a MAFia and its on the right setting as well. Here is my dyno graph,

The only two things I can think of that might be wrong is, MAFia is bad or my mass air meter is not at the right angle(how it came stock). I heard that could throw it off but dont have a clue. Any suggestions or anybody available to lend a hand?

Thanks in advance..
