Hondata re-flash

Hondata re-flash
Had my TSX re-flashed in August of 05. It is a 6MT. Also installed an Ingen CAI at the same time. Have had the car to the track (Summit Point in WV) on 2 different occasions since the reflash. Here is the problem.
When I had the reflash done, I could tell quite a bit of difference in the performance, now it seems to be the other way around. Car doens't seem to perform as well and is not as fast. Also seems to have some hesitation when accelerating either is a curve or straight away.
Is anyone else having the same issues?

I've noticed that I'm used to the power-band flattening of the Hondata reflash. Don't forget, it doesn't raise your peak power, just smoothes and lifts the upper-middle part of the hp & tq curves. I also think one has to add headers and, quite possibly, high-flow cat to get the most out of the reflash.

I don't know what that would be -- maybe the reflash, maybe a fuel-system problem or fouled plug? Is it throwing any codes? What RPM/gear is the hesitation happening?
I wonder if disconnecting the negative terminal for 30+ seconds and allowing the ECU memory to reset, so to speak, makes any difference. I have read on the superhonda site that this is something people do from time to time with Hondas. The TSX's ECU is adaptive, I know, but it is a computer after all and -- using my p.c. as a terrible analogy -- sometimes they just like to be turned off and turned back on.
Beyond that, since you're working with Hondata it sounds like you're working with the right people. Just some suggestions off the top of my head.

this can happen on both a straight away or coming out of a turn. This was not an issue before re-flashing the ecu.
Thanks for the suggestions.

So you have a 6MT?

In stock form, the vtec engagement is 6000 with the rev-limiter set at 7100.
