    Just for everyone's edification, and if anyone is teetering on getting a tune from Allen, I am posting a graph of my MPG that shows how it was before the tune, and how it will be after the tune. This is all city driving, and I have had a very heavy foot since the tune. Also, I've been having some timing issues, which Allen is correcting (damn GA gas&#33, so the MPG might make even better gains after that. I expect once I re-learn how to drive "normal," I'll be getting even better MPG. This chart is my MPG as of 6/13/2005



    Also, Allen, is there any reason that a shift kit would help my tranny since I already installed a Corvette servo (manufactured by TRANSGO), and you increased my shift firmness?

    For those of you who like to see numbers, here are my numbers. As you can see, the MPG has really flattened out a lot since installing the tune, whereas I was getting a lot of ups and downs before. Geez, look at my MPG on 5/3! 10.17 MPG! Anyway, the MPG gains were my way of rationalizing getting the tune to my wife. If it will save us money in the long run, she is all for it. If I get a little boost (or a tiger in my tank, as i told Allen) because of it, then so be it
