Help. Positive Charge Deviation...
Received DTC 17965 for positive charge deviation. The dealer replaced the charge pressure control sensor under warranty, but the problem still persists (goes into low boost 5 PSI after a few minutes of driving). The dealer appears to be unsure of the next steps and is starting to question whether my aftermarket parts are contributing to the problem.
Anyone have any ideas on how to diagnose this problem? Thanks.

Re: overboost may be caused by....
Thank you very much! I'll try to look into these issues before going back to the dealer. When I asked the service manager about other potential causes, he said that my Neuspeed exhaust would be the next item that should be investigated... (WTF?!?)
