Undecided which tune I wanna do...any recommendations from those who have either? Not really concerned about the $$.

primetime

I would say you can't go wrong with either... I choose APR because I have used them in the past and they were first to market, way before everyone else... Both have good customer service and are on the forums... Performance will be about the same... Also, not that it matters but GIAC does the tuning not AWE...
