well here we go i have a 95 wrx got it mapped by jgm in june, car is standard apart from full decat 3" dump valve, and a few other bits nothing mad yet.. car was running great for about 2-3 weeks after the map (1.1bar) clutch went knew this would happen simon said it was on its last legs, but when i am in 5th gear on full boost the gauge jumps about and the car boosts on and off repeatedly and i feels like it loses power after 5500rpm?????

i have pressure tested the vacuum hose checked the coilpacks removed the dv and blocked it off and removed the boost gauge but you can still feel the boost come on and off repeatedly also cleaned the 3 port.... cheers
