I was running 93octane, factory plugs and I have a full printout of the wideband02 readings however they are locked in the trunk right now. He was showing me how rich it was on the bottom end but it leaned out pretty good right before the pop! I'm thinking it was 10-1 or so for a few seconds then the boost just went through the roof and the motor popped...this was WITHOUT the MBC also. I think the wastegate hung or something.
Again, sorry to hear that. So you were at *stock* boost levels (aside from if the gate may have hung)? That is actually refreshing to hear (no offense), but it means something went wrong, not "you blew it up" by boost, etc..
Man, I was planning on dynoing at 11 psi, 15 psi, 18 psi and 21 psi (if it held up after the previous runs

).. I have done several 3rd gear runs from 2000 to redline at 18-21 psi to see if it hods together so I don't drench the poor guys dyno with oil

. I have had 0 issues aside from the clutch breaking free twice

.
I know on the DSM's #2 is the hot cylinder, could be the same here too- I wonder if it went too lean for the octane and detonated.. Was there any audible detonation prior to the pop?
I am still in shock here- I have been hammering my car for 6700 miles at no less than 10 psi- and I do NOT drive it easy with no problems- knock on wood

.
I hope you don't mind discussing this, I know it sucks to do, but I just want to figure out if it is a frail motor for the MSP or a tuning issue for you.
