MSD Atomic Transmission Controller

Just wanted to let you guys know this MSD transmission controller works pretty well in tuning the 4l60E trans. I finally feel like it shifts the way that I drive vs. what the factory wanted it too.

How well does it integrate with the rest of the system? Looks pricey but that's cool that it gives you better control over the transmission.
