Like others said I think it might have been running a little lean, but these motors are not "proven" either...so you add the lean condition + track day heat + a little off balance then you get...failure
Yes it was done though I cant remember the AFR ratios. We did a couple of runs on my car and he used a knockbox to check if there was any knocking. None. We went on road to fine tune and back on the dyno to check again. All perfect.
I had the car running really good for 6 months after that driving the light out of it and on the 3rd track day, it went bonkers. I agree the heat played a major part in the failure accelerated by the tune and perhaps some off balance. But it would have happened to me even in stock form, maybe itd just take a little longer.
