Any update to this??

mine doing similar... map 5 made a crazy noise like a jet enigine (Or metal scraping as described here) ... I often get over boost. and then it looses power. Ive noticed a bit of smoke just recently and a misfire when starting cold ... have I blown up the turbos or something? ... also had the super knock code when WOT sometimes... so dissapointing ... i want powwweerrrr

what was the solution in the end?

I get an injector shut down too... Im starting to think bad injectors?

i get codes for misfire on cylinder 3 and 6and injectors shut down on 3.?
