I am running the same eBay chip in my 1992 LH module. Some comments:

1) There was no gain in peak power. Period. Tested back to back at the dragstrip - zero gains.

2) The cold-shift delay is still present on my car even with the chip installed.

3) The top-speed governor is removed, however, I never was able to test with the stock chip to see if the original chip/module *did* have the governor in place. My current setup (92 module with eBay chip) will pull to 6400rpm in top gear, though.
