GTM Stage 2 Supercharger Preliminary Testing Results

I can pick it up in Europe for around $800 (It lists for 595 British Pounds for the unit with traction and launch control).

The wiring is not complicated at all if you are willing to hack up the existing factory wiring. It could easily be done in less than a day with a factory service manual and the Race Logic instructions if you are technically competent.

I think it is great that GTM is offering this as plug-and-play, and if you think it is a good value, that is all that matters. I personally wouldn't pay $1500 for a harness, but there is definitely some appeal to doing so.
