Double Dark Side! Diesel & 8P
Ok I'm a bit miffed! I've just done another run with my DV back to the normal position and I got almost identicle results to having a reversed DV:
22psi from 2800rpm to 4100rpm then it starts dropping off till it reaches 15psi at 6000rpm!
Now how was I getting 257bhp 6 months ago on a warmer day (12 degrees) with less boost with the N249 connected? Could it be that where the N249 is no longer able to open the DV I'm holding more boost and my standard tip is collapsing at 4000rpm?
any suggestions guys?
