My guess is your on stock charge pipe and DV's is that your DV's are leaking boost back to the intake side. Some guys that were pushing boost that had the stock DV's would get that code and solved it by upgrading.
All I'm running is more boost. Everything is stock.

I'm not sure how my mechanic checked for leaks and to be honest, I'm not confident he did.

You're saying people upgraded their DV (diverter valve)? How is that done? Where can I buy the part? I'm eager to solve this because getting limp modes on the track is kinda freaky.
