Thanks Jack that is a ton of help to me and I'm glad to hear that, and its also good to know about the jump starting deal i was just always under the impression that you had to set it back to stock but better safe then sorry i guess.
But i normally do all my mpg stuff hand calculated and once i started playing with it again it seems to be doing a little better my tire size was just a hair off so that could maybe have a little to do with it but probabaly not really haha.
thanks again much appreciated, this site and company is Awesome!
