1.8T & K04 LCR.
Right, so the car revs to redline and boosts somewhat but it's lost it's urgency and punch in the back, obviously acceleration is slower too, much slower. I have no fault codes and ive tried all three DVs (007, split-r and OE) but I have noticed that the DV blow off sound is quieter so I guess I've lost boost somewhere.
The car was fine yesterday morning, gave it some beans & it pulled hard. On the same jounrey I went to accelerate again and where it would normally throw me in my seat at 2500rpm, I get nothing, just hestistant (in comparison) progressive power, almost like NA. Does this sound like a boost leak? I've checked the TIP and all is secure so I'd guess it's post turbo...or something else? Where should I be looking?
