Has anyone been to the track after getting an ECU tune?

[stonebreaker]

I finally found my copy of Desktop Drag the other day. I put the stock power curve from GM Powertrain in for the Redline, and then I went to BSR's website and put their numbers into a power curve. Now, even though the peak numbers aren't all that much higher, my drag racing program seems to think the bigger torque numbers in the midrange are worth nearly a full second off the stock quarter mile ET. In case some of you guys have never been to the track, that's HUGE.

Anyway, I was wondering if anyone had some real-world numbers to share. Desktop Drag has been very reliable for me in the past when I was bracket racing my Impala, but it's very sensitive to input parameters - garbage in, garbage out - and in order to evaluate what it's telling me, I'd like to get some real world data.
