I'll start digging in soon.

Oh, I did get a P0422 before I noticed the overboosting.

The BOOST is back!!! Volvo 850 T-5R overboosting - Performance issues - YouTube


You should go find that 245 brick and give him a taste of his own medicine while you still have the boost. How did you get it back?

I know the Ultragauges do.

LOL, great idea, however, when I went to "bust a move" on someone this afternoon, the power was gone again. Yikes!!!
