should get it by Friday. The place I called for the group buy is a Saab dealership. You want to talk to Brad Schaffner at Kansas City Saab. 816-333-6582. He seems to know his stuff about the system cause he was telling how they been putting them on the turbo Saab over there. He also seems like a really nice guy. Just mention to him that your wit hthe GP on TT.net and he'll set you up.
If you ask me why I got the system my 1st respons would be *Detonation*. I push my Z hard at the track so any cushion will help and I would spend a little money now then spend it on a blow engine. Besides it cleans the engine, and lets me have more hps that I otherwise would not cause of hot weather and yes I have done my research on it. I have wanted AM for a long time(1997) but did not know of any Zer's that had it in their Z. And now that it has been done and shown to work for the Z I buy one. :)
