Did a commute to work and back...balmy 40 degrees out, but clear. Very impressive pull! Definitely how I had hoped a new purchase should run/impress one!
The pacing cars just melt away in 4th gear :-)
Bad on me, I found data logs past the OEM redline of 6500 rpm. I'm not consciously exceeding the limit on the gauge, but either my 'mature' reactions are growing worse or the tach is a bit tardy. Nonetheless, I will have to adapt to shifting prior to redline and possibly swapping the OEM valve springs for slightly stiffer ones to allow for my miscues.

So far the upgrade is well worth it - not inexpensive (every nut, etc = ~$8000), but then again, bolt it on (with program) and you have 650 HP with OEM driveability. (However likely the mileage will never be the same... ;-))
