Nothing wrong anywhere with the car as such, just the mods are wrong what you have carried out and/or a faulty N75 valve. The map was not pushed too ard due to 120k on the turbo and clutch. Which is the window for failing parts... But saying that Steve-PD have 150k+ with a 30psi over boost and no issues.
Our worry was that the car came in stock over boosting to 30+psi for around 400rpm then under boosting, its common for stock 150PDs to see 30psi plus for year and go un-noticed without any issues. The remap is pushing the boost harder but not the peak boost, I would be happy with 27psi peak and holding 24psi which would give 190+bhp 300lbft with the correct fuel setup.
Post remap you was still seeing 30psi peak and 3psi undershoot at the top end which you can see on the graph as a dip. I was happy to do the car if you was going to sort the overboost out asap and drive in normal until you got the boost doing what its told to do by the ecu. Logs on block 011 & 008 which give you a visual picture.
You need to fit all the valves and pipes ect back inplace and just blank the anti shudder valve and EGR. Then get the car logged, once you got all the hardware correct then the power will substain at the top end and give you a higher bhp reading closer to 190+bhp.
The VNT was nice a free so dont worry about that, just sort vacume control system out and get her logged and checked out.
Keep us up dated..
