So I pulled the trigger on a 2010 Grabber Blue GT500. I've always wanted grabber blue and the 2011-2014 were out of my price range. On my 2007 GT500 that I traded in I did an JLT intake, a tune on my old SCT Mustang XCalibrator 2 Tuner, a blower and idler pulley. I gave the tuner to the dealer because I read it wasn't compatible with my 2010. That being said, I want to move ahead with doing something similar on my 2010 Shelby. I'd prefer to keep it as stock looking as possible. So my question is, what is the most cost effective tuner out there just to load a tune with no bells or whistles? Second question is, can I achieve the same power increase that I did on my 2007 keeping the stock intake? Last question is, is it still advisable to swap out the blower pulley and idler pulley? Really appreciate it!
