Everything went smoothly and I received my ECU today. Trav, (silvered), was extremely helpful and great to work w/ and even gave me $400 off

($600)
So I plugged everything back in, burnt myself FOR THE SECOND TIME on that burning hot fluorescent lamp that's behind the carpeting, and turned on the engine.
Immediately, the engine sounded a VERY TINY bit deeper than it did before. Not something you would notice unless you drive the car every day.
They told me about 50 miles would be enough for the ECU to adapt and that it would take shorter depending on how I drive. I beat the crap out of her today...
I drove everywhere I could for any reason I could. Red-line 1st, red-line 2nd, I even red-lined THIRD once!!! (5 speed)
However, my problem is that I can not tell if there are any gains or not. It sometimes feels a bit faster, but I do not want to fool myself into thinking there is an improvement when there isn't.
Does it feel different? Even that I can't tell. It seems like it does...maybe a tiny bit faster. I'm not sure. Maybe there's someone in the area w/ a 987 5 speed who would be willing to drive my car and see if there is any difference.
One thing that concerns me:
At times, it almost felt as if certain points in the powerband gained and lost power. They assured me there would be ZERO losses at any part of the powerband, but who knows?
Anyways, I just wanted to report for those who were interested. I have 2 weeks to try it and I can return if I don't like it.
If anyone in the area (50 mile radius?) wants to give it a shot and see if there's a difference, I'll drive over to you.
Thanks for letting me blab
