Hello. I'm looking into tuning my Mk6 GTI and am stuck between United Motorsport and GIAC. I'd include APR, but the highest they now offer for the stock IHI/K03 turbo is a Stage 1+ tune. I've already got a full turboback exhaust so I'm not inclined to source an APR downpipe just to go Stage 2 with them. UM has a K03 ECU/TCU combo for $900, while GIAC's Stage 2 is $1100 (I intend to go to a shop that offers all three of these tuners). I've heard of UM's success in making one of the more powerful tunes for the Mk6 R's and one user (a GTI I believe) claiming that they beat all other Stage 2 tunes they've come up against via UM's K03 tune, and I also know of GIAC's 1/4 mile times posted here on this thread as well as their "Clutchbuster" tune, but that $200 price difference has me undecided on whom to choose. Has anyone had experience with both, and what would you recommend?
