Fuel cut is quite dramatic, and usually freaks people out, yet no mention of it. I ran with the p0420 idea since p0240 symptoms were not mentioned. I could be wrong, but I do know the difference of the 2 codes.

The big question is: what does the little piece of paper on JML281's dash say

You are correct, until the OP can verify the actual code no one will be able to help. Fuel cut due to overboosting is quite dramatic and pretty unmistakable. There is more then enough info here to help the OP be the code 240 or 420
