Hell yeah, i will have to try this after my last final today =).. So it will never do that adaptive learning crap again? or is this just a temp fix like re tuning it?

What is a VMP tune? I see in your sig you have the glass roof option. Do you leave the cover open most of the time? Are you glad you got it?

Also, lets not forget about how heatsoak, now that we're seeing warmer ambient temps, will really sap our power.

Yes, the glass roof option has a sliding mesh cover to block almost all of the sun. Go check one out at a dealer.

As stated earlier, reloading the tune doesn't reset all the parameters of the adaptive learning function that lifting the battery lead does.

Glad I got the glass roof, pretty cool. The glass cannot be removed. There's a shade you can pull to cover the glass from the inside, but I never use it.
