Hope someone can help me, After nearly 2 years of my car running boost of 1.2bar it has now decided it doesnt want to. Through the gears it will only boost to a maximum of.98 but on the a19 in 5th it will shoot up to .98 then slowly creep up to 1.1 then drop back off, creep back up to say 1.05 back off again etc etc.
A friend advised me to change the plugs and check coil packs so i have changed plugs and all of the coil packs are ok but the car still has the boost problem.
Oh and before i forget its a k plate wrx, td05, ported headers, yellow injectors, front mount intercooler, hks induction kit, 3 port boost selonoid and a w6 ecu chipped by scooby clinic

could be lots of things, boost leak, faulty map sensor, weak actuator, burst/split hose, compressor wheel is worn, exhaust turbine wheel is worn, faulty boost gauge, ecu retarding timing anything, just pick one!

I think i may of found something here, On the intake manifold there are 3 pipes one goes to what looks like a regulator of some sort that is attatched to the fuel rails the reinforced pipe that is attatched to this regulator looks like its kinked would this cause boost problems??
Ill get a picture up so you can all see what i mean.
