Again I'm not going to talk kw gains as I'm still not 100% convinced on the CES gains myself from my Dyno readings, but these are done in less the perfect circumstances. Suffice to say my original Dyno, Stock, was 115.0kw, with CAI 1 month later it was 119.8kw, with CES 6 months after the original reading, the CES had been on for ~4 months it was again 119.8kw, and this weekend, following several swaps between by stock airbox and my CAI and a new MAF sensor, and ECU reset the day before and ~300km run in that was not ideal highway driving, it was 115.3kw... I know what you mean by the clutches as mine was one of the worst, until it was adjusted 12 months ago and I've loved it ever since.
