chip vs stock throttle behavior. (archive)

I recently purchased a 1991 M5 with an Autothority chip already installed. I also have the stock original chip.

Most of my driving is highway, but sometimes bumper to bumper rush hour traffic. Going from no throttle, to part throttle with the chip is very harsh on the transmission at low speeds. I'm thinking this may be due to the fact the chip is designed for more immediate throttle response. The stock chip may be designed for a smoother transition. Is this correct? If so, I may try switching back to stock if this is the case.

Can someone who has experienced both, please comment on the differences between chip and stock in this respect.

Since this car has 6 throttle bodies, will the chips make any difference in this respect?

My 1987 535i 5spd was so easy to drive in traffic.
