As you stated above, you picked up your car, the clutch was slipping.
That means that your clutch couldn’t handle the power that the tune produced. Than you go and have the car re-dynoed with a slipping clutch
What the hell are you thinking :banghead. It’s simple, put your car back to stock, and quit while your ahead, Bottom line, it seems that the tune produced too much power and that’s the issue. A 2nd dyno shouldn’t of even been attempted with a burning clutch. As far as your clutch goes , if it is new as you stated, you didn’t break it in properly, or you spun the heck out of it and glazed the clutch and flywheel, either way, I’m surprised the 2nd Dyno showed any gain with the clutch slipping, also I looked at F1Tuning’s website and the 30% gain is on turbo cars, not normally aspirated.
