5-Star or SSi from my experience.

I have an Ssi on my one 6.2 and canned sct on the other 6.2 I own. Being honest. ... i can't tell any difference other than the canned one shifts at the rpm I want it too and my custom one shifts too low of rpm and doesn't respond to any changes I make when I load it. This is why I own HP tuners.

Dyno sheet below is on 93 octane and shows about 31hp over stock, at the wheels. You can also expect improved throttle response and shifting.

Im using a tune from SVC. Very happy with the results. Power when I need it, very little throttle lag, but very well mannered for daily driving.
