looking at getting a adaptronc and this is one of my mayor concerns about tuning my car and running more then my power cards.

Worst-case scenario, if you're really tuned to 10/10ths, you can just pull a few degrees of timing when you find yourself in 91 Country.

we're going to find MBT or detonation, and back out 2* in either scenario. Then if you want to run the 91-octane we'll pull 3 degrees out and listen for detonation with det cans.

What I want to know is how you got an animated gif as your avatar. They always froze for me.
