SS #670 Modifications:
Early on a bought an AutoTap ODBII scan tool. It worked ok but later EFILive came out with software that worked with the AutoTap cable. It uses the faster GM protocol for communications, had bi-directional control capabilities and seemed nicer than AutoTap so I bought a license and upgraded my cable.
Later EFILive came out with their FlashScan cable. It uses USB and can do black box logging (without a computer). But it also allows PCM reprogramming. They offered an attractive upgrade deal for their current customers so I immediately upgraded (order #52).

This allow me to disable CAGS without using a !CAGS kit. And changing the calibration also disables the annoying SKIP SHIFT dashboard light.
|EFILive speedo page|
My speedometer error is about the same as it was before the gear change (it reads approximately 1 MPH low at 55 MPH).
Removing this is pretty much just for bragging rights.
|EFILive fans page|
At first I thought that the HPP3 settings were too low; my fan would sometimes come on while doing 20-30 MPH up hills. But I tried running with the stock parameters and found the temp would run about 10° F higher so having the fan on when not at freeway speeds does help.
I highly recommend EFILive and FlashScan. You don't have to pay for updated software. They are very responsive to customer questions and have an active bulletin board. Reading and writing the PCM is very fast, usually under 2 minutes.
