Looks like it can do what SCT already does.
If you're looking for something to control the shifts better. Then you should take a look at the bauman controller with harness for the 4r transmissions.
The other idea is to get a manual valve body from Freddie brown.
The only thing I like about this is the ability to change shift programs on the fly. Stock settings for daily driving and race settings to lay the smackdown and the track :shrug:

If you didn't eat so much subway you could drive a manual
Noooo, stay away from those. You don't want to crank line pressure to make the tranny shift harder. You want to use the Jmod which is a simple DIY modification of the stock valve body in your car. Trust me I blew my first and 2nd 4r70w from cranking the line pressure up. The valve body mod is what I should of done the first time on my F150.

I can drive a manual just fine
I know, I was joking about your thread the other day lol
Just had Subway for dinner Mmmm Mmmm
I've ridden in a B&M shift kit 4r and it was a neck breaking shift all the time part throttle or fill throttle. The j mod only shifts hard at WOT and smooth at part throttle. I love hint the j mod is cheaper as well. Not sure mine was modded by Darrin who used to build a these things.
Do you happen to know how many actuator springs were left in or were they all removed. According to TCCoA articles, all actuator springs are to be removed. Im finding a few people say that the transmission was too harsh even at part throttle so they reinstalled a spring.
