cheers all for the reply's
i have dialled it back to 10 psi and it has improved but is still there.
When hot the vehicle hesitates/surges i have tried 98 and 100 ron fuel
i thought it might be a battery problem so i replaced to no avail
will pick some contact cleaner for the maf and a fuel filter as well as some sparks tonight
mods: sh*$y drift boost controller, stock BOV, stock intercooler, pod filter
PS: the vehicle smells very rich after snapping the throttle open
regards
aphex
