Think my cars over boosting lads, I took out the plugs and they were pretty white, no damage atall to the ceramic centre etc, but they were a bit white, not to bad

is it possible that a leaky pendulum chamber gasket can cause over boost, it cuts out if I totally floor it in 1st or second and ive recorded boost spikes at as much as 1.76 -1.8 bar

at the mo, ive changed the plugs and im using optimax and 2 cans octane boost per tank,

but I think ive got an air leak will this cause it to over boost ?

cheers Glen
