well i just read on the cobb tunning website that both stage 1 and stage 2 maps dont allow you to have anything more than a cat back exhaust. what are those with intake, test pipes, plenum spacers, etc. supposed to do? according to the website any of those with intake mods will be running extremely lean a/f ratios. theres no way around this?

 

what is the average hp gain??? i have intake, plenum spacer, test pipes, cat back. will this make my car run leaner than it all ready is??

 

Is it available for a 2007 G35 6mt Coupe?

 

Sorry for the delays guys, i haven't received emails about the posts, I will contact cobb and find a way around this and PM you all in a few hours.
