HELP!93WRX Fuel cut at 0.9BAR
ive got a 1993 WRX saloon manual,its got a Blitz nurspec R 3inch exhaust system, magnex twin dump decat downpipe,magnex turbo up pipe,HKS induction kit,Toda racing flywheel and AP racing clutch, everything else is completely standard inc fueling and ECU (always run on shell Vpower), basically the car has got a intermitent fuel cut in 3rd and 4th gear once the rpm reaches over 4500k, its currently boosting at the standard 0.9bar and never goes past that, the strange thing is the car had a full rolling road diagnostic tune from power engineering 2 months ago which showed 275BHP and267 LBS/FT peak torque at 5850rpm, and everything was 100%, the fault just developed since i put the TODA racing flywheel in and clutch, which is extremely strange, any ideas??any help very much appreciated,many thanks

Have you done an oil change or topped up the oil? First thing I'd look at is your boost solenoid and associated plumbing to make sure it's not full of oil - sometimes just happens after a while, other times it happens pretty soon after an overfill of oil.

it's definatly your boost solinoid clean all pipe work and solinoid itself with brake cleaner or degreaser you can get them both in aerosol can done mine yesturday and its now fine check your oil level though keep it in middle of empty and full mark or solinoid will clog again
