I have an 06 GT that's heavily modified with Comp Cams XFI Stage 2 NSR Cams, Magnuson MagnaCharger Intercooled Supercharger, Steeda CAI, JBA Cat4Ward Headers, FRPP 4.10 Gears, FRPP 62mm TB, MAC Pro Chamber Mid-Pipe, Bassani Axle Backs and a few minor items. I've purchased 3 email tunes over the years (bought car new in 2006, supercharger installed in 2010) but she doesn't seem to have the seat-of-the-pants raw power I was expecting from this combination. Could it be that some of the performance mods are working against one another? I'm sure that a dyno tune would dial it in but wondering if it's money worth spending since the email tunes supposedly took into consideration all of the mods. Thoughts??
