It's absolutely foolish to be running that car down the track and not closely look at the data, actually, you shouldn't even of gone to the track and your tuner should of realized this as a MAJOR PROBLEM.
Case and point, similar situation as you, except I didn't talk **** for months building up to this so it didn't attract near as much attention. About 10 years ago I build a turbo'd car, lost a motor. I did the same thing as you and just guessed what went wrong. My datalogging system was screwing up, but I didn't think anything of it as I was convinced I knew what the problem was. Build another motor, and pop it. Same issue. Didn't have data. Built another motor, figured out my data logging issues, and found out that we had a wastegate problem and the car was seriously over boosting (data doesn't lie). Something that was so simple cost tons of money. Could be the same in your circumstances as well.
You have the "technology" so you say, use it. Your tuner should know better than to send a car down the track without knowing 100% sure that the datalogging system is working.

I'm gonna keep Drooze out of this. He's a friend and co racer dealing with new learning curves. He's had his fair share of ups and downs and I wish him and his crew well. I do agree with your comment about his tuner. His engine also add's another factor into the mix as well.
Anyways.....I don't know you, nor you know me, however you brought up very valid points. For me, data logging and active knock sensors are my new best friends. If it wasn't for those, I'm sure I'd of oiled down a track or two in the past 4 years.
