Superchips

[jmoffatt]

Finally got a superchips cortex yesterday and installed the 87 octane tune in my Alpha, all I can say is WOW! this 5.3 has really woken up.
I can't wait to try some of the other tunes.

I love the SC Cortex for my H2; I just wish they would hurry up and make a tune for the 3.7l I-5!
