I'm late but ill add my PERSONAL experiences here. I won't recommend MStuning. Always heard great things but I bought a car already tuned by him felt and ran great, no need to adjust anything but the transmission tune must have been off. The 1-2 shift was slipping bad at the track. So trans was burnt up a tad earlier than it should've been based off my experiences in other builds.
That said I've always had great luck with HHP, used them for several vehicles and they are always my personal first recommendation.
