I've been looking around and I haven't found much about V guys doing this. the heatsoak on the maf/iat is ridiculous and kills the power. I found a lot of gto guys buy a harness and sensor and relocate the iat over into the filter element and out from behind the radiator.
anyone here done this same mod on their v? http://kb.ls1gto.com/KB/article.aspx?id=10279
when the maf gets heatsoaked the power loss from timing pulled is insane. this is something i'd only do on a n/a car.
