The following mods are upper/lower cobra intake, bbk equal shorties , some no name brand o/r Hpipe and mac mufflers, underdrive pulleys and a recently purchased C&L air filter intake. The intake came with a 76mm maf housing and sampling tube calibrated for 19# injectors, I still have the stock throttle body. Anyways the problem is the car runs lean, during the dyno pulls at idle it had a fine a/f ratio of 14.7/1 and during cruising it stayed perfect, but as soon as the guy got on it the a/f went to 15/1 and it stayed there all the way up to 6000 rpm. The tuner told me is running way to lean during wot and that the C&L is whats making the car go lean, he said because of the bigger maf housing the air going in it slows down and the sensor does not read properly but I think that's BS because our mafs have a separate port that the air has to flow for the sensor alone and it does not matter how big the housing is. You guys think the maf thing is true ?</p></blockquote><p></p>
