did you go from side mount to front mount? did the location of your MAFS change? i know this sounds obvious, but did you check for boost leaks on the intercooler couplings? pinch off the blow by hose that runs to your pcv valve, if your engine speed rises then you have a leak, if everything is ok then it will idle rough when you pinch it off and then go back to normal after releasing.
