Haha, I bet it can drive Bill a little crazy because he can never be 100% sure how a truck will react.

I like the way the truck feels at +0 better than with advanced timing. It just seems to pull harder. I'm not a racer, just normal mixed city/highway with light hauling and towing. I will try it again at +.25 now with the cooler weather and see if it makes a difference.
Also my idle seemed to smooth out at +.25, now at +0 it is slightly rough at times.
Thanks for the input, I think ethanol may be here for a while and this may help sort out if we can tweek things to better advantage.

^That is very similar to what was going on with my truck. Haha, you'd think that since they are machines off of an assembly line that they would all be the same. Sure is strange.
But I guess it's those quirks that keeps Bill in business.
