The car has more power now but that could be just down to me fixing a leaky boost hose which has a split rubber seal!

usually by reading threads from forums and such it sounded like to me your turbos are on their way out, well at least one of them you will still can feel and hear it but because it has lost its step the more and more you use it the more and more it will finally give up thats probably why you don't feel the punch like it was before because its about to go out on you completely but then again, i am no master tech, i just read a lot of stuff online of people that went through similar fate |

Cyl#6was replaced and coded/learned into ECU.
Bank replacement is recommended but not necc. The car did run perfect after it wasnt until 5k KM the car started with this. Also full re-adaptation dde done- no change. Will try no MAF/HFM tonight and re-adapt this time.

Hey I know this was a few years ago, do you happen to remember what the issue was. I too replaced both PC and the front one is showing 1 Hg vacuum (both new and old). Not sure where to go from here as clearly it is a problem before even escaping the solenoid and getting to the bypass.
