right guys need a little help, my cars boosting around 0.3bar, iv cleaned out the boost solonoid, it clicks like it should when in test mode. and it made the car run smoother, so i believe thats working.

now the next port of call is the actuator. i tried moving it and its extremely stiff, almost seized. i understand how it works if its too soft the boost will be released to early, is there any way say the actuator has got stuck open slightly so its releasing alot of boost?

the cars a wrx classic with a td05
