OOPS, just saw your sig. You're a stillen guy. My apologies. I saw one of those "so perfect" stillen tuned superchargers up against a GTM on a dyno. People who have installed both speak of the fitment with the stillen and how it makes you fit your car to the kit rather than the other way around.


Either way I feel terribly for the owner but why he would romp on it without a tune is beyond me.

Just goes to show he simply wanted to go fast and didnt have the knowledge. I'm not saying he had to build it himself, but to invest all that money and not understand that he shouldn't get on it until it was properly tuned doesn't add up. It's really his fault. If all he wanted was power then yea, lean it out with the current set-up. But he should have told the tuner to leave it a little on the richer side if he was planning on headers all along.
