Reading this thead brings back bad memories, Sorry daggo I too spent close to 10K at Slackos Everything he put on the car has now be replaced. (except valve springs) Unichip Exhaust 42' injectors clutch And a few other bits and pieces End result was 326hp on Slackos dyno and 330 hp on MCE dyno it does not read that much lower! And his excuses why he could not produces the bigger numbers like other tuners over east at the time was that they have better fuel and better quality of air. I see you have the edit, Does tim do his own tuning with the CAPA software? Unless things have changed alot (this was back Jan 06)I would recommend you take you car else where. Russ
