i had my IP calibrated recently , but i'm not happy with the result...i was expecting a night and day difference in terms of power. The car does idle smoother and starts easier, so i guess the IP job went well...injectors weren't touched btw... will have them balanced some other time...

anyway, these are the symptoms... off the line the car isn't that sluggish, and not too fast either... it feels just right so no issues there... my problem is when the car starts to pick up speed, it feels choked... when you step on the accelerator it SLOOOOWLY picks up speed... so i am clearly either not getting boost or enrichment...

don't have a boost gauge so i did the preliminary checks concerning plugged ALDA lines etc... all is clear

next I checked to see if the turbo vanes spin freely (engine off ofcourse)..this is where i'm having issues... with steady finger pressure the turbine spins freely up to a point then starts to stick JUST BARELY...then spins freely again... so when you try to spin the turbine with enough force it won't freewheel an entire revolution... is this a STICKING turbo issue? or is this normal?

Anyway... i managed to remove the turbo this evening...what a PITA!!!!!
the hosing, external, was all gunked up... i was thinking of opening it up and cleaning it myslef but after reading a ton of threads I might just opt to have it inspected/rebuilt/cleaned just to be on the safe side.

so before going ahead and bringing it to a shop... anything I should check on my own? should i just DIY it and just clean the thing?
