Shit, enough with the venom for GIAC. Without Garrett Lim hacking and reverse engineering VW's ECU code as a med student in the '90s, (and then forming GIAC) chip tuning wouldn't be what it is today. In that era, people were really puzzling over the software, Garrett was one of the first guys to really figure it out.
Their tune is not bad, I've driven it. I don't believe it fuel starves like somebody was implying. The car I drove had been running it for over 50k miles with zero problems. It is expensive. They probably don't sell that tune enough at this point (if at all) to bother adjusting their price down. FWIW, the original owner of my car paid Hoppen $2300 for the stage 1 MTM tune.
I am a little biased, as I run GIAC in my 1.8t and have been really happy with it. It's a great tune for that platform. I wouldn't run GIAC in my RS6, I'm happy with MTM. But I also wouldn't run home-brew software and beta test for someone else's start-up. We all know how that turned out.
Back on point, looking forward to Pat's dyno of the Viper software!
