Really? Depends where in the rev range it makes that amount of boost.....
Glenn, octane booster can affect the 'colour' of the plugs I believe, you certainly shouldn't need two cans of it with Optimax imo.
Is it doing that with a full tank of petrol now then too?
its hitting 1.7-1.8 bar boost about 4k rpm in 1st and second mate, and yeh same with full tank fuel
heres a pic of a plug mate, but im pretty sure this is an air leak / gasket gone / damaged
