after doin everything fule related to fix the ' boost cut ' style problem i was getting & not having any luck i descovered that the only time id hit ' cut' is when the boost would spike to 22psi.
this lead me to the only conclusion left after exhausting all other avenues, that maybe despite being gapped to .66mm, the spark was being blown out at these high boost spikes, causing the 'boost cut' style hesitation i was experiancing.
the fix : plugs gapped to .45 problem solvered.
the only thing is, iv never heard of anyone having to gap their plugs that close before.. & im wondering if going to bpes8's will make a difference to the sparking performence? running 7's atm.

on the bonnet it recommends 0.7 - 0.8, i think when you buy the plugs they come gapped at 1.1mm
how do you find the 7's tharaka? I was running them before but I found the car a bit rough when cruising and they fouled up a bit.
I'm using 6's now and haven't had a problem but I'm thinking I might have to change to 7's when I up the boost.
thoughts?

6's were misfiring in 4th at the drag day
and i put the 7's in the next day, but never got a chance to test them out
they never misfired or anything on the way to work
you should get an AFPR to stop your plugs from getting fouled while you're idling

bp8es plugs drive like your normal bp6es plugs.. they dont show any signs that they are colder in respect to normal driving.
i had mine gapped to .6mm and they were great.. never had any issues with them.

so its excess heat that causes the plugs to not function properly? hence going to a colder plug ?

heat/boost are the main issues.
