Well a guy on the forums ran a 12.9 with a similar setup to you and 207rwkw on stock turbo... me on the other hand ran a 13.8 @105 with 244rwkw, there is something wrong with my car but what is it? incorrect dyno? setup? clutch? thats all im saying, and my car has been on a few different dynos with the same tune pulling very different figures. The car drove 100% and with fantastic power delivery, so dynos dont tell the whole story..
