Honestly your best bet to get an APR group buy together is on the vortex.
Here everyone pretty much swears by GIAC and as a plus EPG is a sponser as far as i know. Or atleast did the work on pauls old gti which is reason enough to go GIAC from what they did to that car. They also did my old 1.8T and it pulled on my buddys APR chiped car same basic mods just a diff DV. APR does do the 100 oct program and he pulled on me pretty good on that though cause he had the one that you can change the settings on the ecu.
I think GIAC does the same thing as far as switchin setups on the go but both are a good bit more than just getting one program flashed.
