    I was in for the race cam, injector, map and Thomas chucked it on the dyno and wondered why pickup was so slow and gutless!

    Quick check found the bypass valve was buggered.

    Swapped it over and yes, added the missing 30bhp back!!

    Tried to put me off the cam etc, as that only added 20bhp and the difference I'd notice with the new valve would be huge. Which it was.

    I still had the cam etc done though!!

    208.4Whp, which I think x 15% = 239.66Bhp?

    I'm a bit mystified by the insurance when having to declare all the stuff I've had done, as it's only increased the Bhp from stock when new by just over 20Bhp!
    Mine was running just below 200Bhp when dynoed by them last year, so had lost some ponies over the last 10 years.
    Insurance due this month, so will give the usual suspects a go, though won't be bothering with my current insurer as they charged me £35 for 2 months after the cam/injector/map declaration. Nor will I bother with Craig's insurer...
