    Don't form a final opinion of the new tune until you drive several days. Every time a new tune is written, the long-term fuel trims in the computer are cleared out. It takes a while for the computer to adjust the trims again, and the result can be that it drives quite a bit differently a week later than it did the first day with a new tune.

    I just drove for about 20 minutes on the new tune and its driving well. Yes, this is without several days of driving. I took logs which will be provided to Prodigy to compare with my last tune's logs. I will say this though, I've have loaded a couple tunes thus far and none were this good out of the package.

    I will monitor and re-log after about a week's worth of driving to see if the tune's drive-ability has changed. Either way, Prodigy was pretty responsive in getting this back to me with my specific topics addressed. I will keep everyone updated.
