Pulled out the spark plugs and coils on the weekend. Coils looked brand new. Checked thier resistance all within a fee ohms of eachother. 6.0kohms I think,.. 2 of the spark plugs were on finger tight. Re dis them and checked the state of them they looked great, cars feeling much better. Cleaned that solenoid and the throttle body. Boost is kicking in harder than ever.. Every now and then I get a little hesitation but it's 90% better.. Thanks for the info henz big help mate.. I might run some injector cleaner next to clear that little bit of random hesitation
