Default Strange acceleration pulse

Ok bear with me im REALLY intoxicated with some friends, but I still need to post this because its a concern. When accelerating in town at 40mph in D (overdrive) the car seems to pull harder at roughly 2900-3000 rpms. I did reset the computer today by unplugging the battery, so the Superchip was obviously recalibrating the engine all day. So first I'm assuming the Superchip is advancing the timing during peak hp at roughly 3200 rpm? Or maybe its just the engine doing that its doing. I'm not flooring it to let it downshift, just accerating moderatly while cruising in the city at 40 mph. So what you think? Superchip recalibrating or just my drunkin' *** talking for attention?!!!!

I dunno.....did you have your 'beer goggles' on too? Might have been too hard to read the Tach with them.

Seriously, when I reset my PCM now with the Jet Chip, it does some weird stuff it never used to do for at least a 1/4 tank of go juice. Just keep an eye on it.
