After going zvh and having lots of issues, would like to thank Iain and the lads at power Engineering for all the hard work they put in and very very cheap bill considering!, i make the 100 mile journey each time due to the great service they provide.

Was aiming for 200bhp, but made 185.7bhp and 196lbft at 15psi, ian told me i should have VALVE SPRINGS to go with my cam which i got 2nd hand,

Still after leaving felt like a different car! and would recommend anyone to visit as all 4 times i have visited they have MORE than looked after me

i was just wondering if any graph experts could tell me.....

Iain said the VALVE SPRINGS were the fault AND I WAS GETTING VALVE BOUNCE hence the graph tailing off but after leaving i noticed the new (600mile) clutch wasnt appreciating the boost and slipping on boost, and im not questioning Iain as he REALLY knows his stuff!!!! but before i ring the lads to bore them does the graph say that too you? or would a slipping clutch show the same sort of graph (on boost?) just dont wanna bug iain if anyone can make sense of it, gunna go for an uprated clutch asap anyways heres a few pic of the graph and car on the rollers

Made up with how well she pulls now although its No high power 400bhp cossie
