Finding a place to do that even in 2nd gear takes some forethought...but I was able to do so quite a few times by the cover of night! The DME is definitely still adjusting because during one 2nd-gear pull I did, there was some noticeable wavering of the power level produced especially around 5k. Seems like it could have detected knock and pulled timing, but continued delivering solid power. I will continue to blow through 2nd at every reasonable opportunity to see if it learns.
I'm generally revving to 6.5-7k. At least once earlier today, when I did exceed that, I noticed a pretty substantial vibration develop--almost definitely on the motor, as it was primarily transmitted through the stick. I do wonder if the new belt is under-tensioned and wobbling as various harmonics are encountered. How much does your belt yield if you push on the section heading down on the right after looping the S/C pulley? Is it really quite tight or reasonable to move an inch or so?
I continue to tread cautiously with over-7k engine speeds but will do some of my standard pre-supercharger 7.5k pulls tomorrow to see if the vibration is always reproducible. Also have to get that inside GoPro footage. If dubbed with audio recorded from an iPhone, it might be decent!
