I think mick was the problem back then, and now with Tim there it is alot better, but i remember a guy i know had his engine blow up on a RPM dyno a few years back, not too sure what eventuated from it, another mate had his car at Tilbrooks for quite some time with no work done and kept getting put off, I'm sorry but Mark has made a few bad calls over the last couple of years in my eyes, won't ever be seeing my car down there.......not even for a dyno day!!!
