Why change shift points/shift firmness??
What's the advantage to changing the shift points/firmness? I'm getting ready to buy the hypertech max energy programmer and I know you can adjust those too, but being a non-techy, I don't know why'd I want to do it.Andrew

I copied this from the Hypertech wbsite so I hope this helps.
In addition to controlling engine functions such as air/fuel mixture, spark timing, and maximum rpm, these highly evolved ECUs also regulate transmission shift points and firmness, limit top speed, and display speedometer and odometer readings. Hypertech engineers were able to use these capabilities to provide additional features for enthusiasts. The Power Programmer is much more than a tuning chip * it is a self-contained automotive tuning computer. The Power Programmer automatically installs the powerful Hypertech tuning program. It also allows enthusiasts to access and reprogram the vehicle’s computer to function properly with aftermarket components such as non-stock wheels, tires, and rearend ratios. A Hypertech Power Programmer is really the most powerful and versatile tool a performance enthusiast can own!Darcy

I used to own a Pont. Ventura 350 cu. in., auto, limited slip rear, Holley 650 spread bore, dual exhausts.
While the car was no slouch it needed a little more oomph!
I installed a Trans-Go semi automatic shift kit in the valve body.
(Only difference between then & now is My mods were mechanical and now you can do the same thing electronically)
Before during normal driving there was a slow easy overlap between all the gears. Hard acceleration only made a slight difference.
After the installation it was like night & day.
Normal driving there was not much difference felt.
Once you floored it you thought someone put a different engine/trans in.
On full acceleration every shift was like I had a manual trans and was banging the gears. The shifts were solid and the tires would even break loose a sec.
I surprised many a car on Telegraph Rd. & Woodward Ave. when I'd floor it from 30 get the tires to squawk all the way through the gears with both hands on the wheel.
You'll get a better performing ride and even reduce heat build-up from shifting.
