I think what the above poster was trying to so eloquently say is that it is never too late to do a tune. I would suggest contacting Kelly or Alvin @ www.pcmforless.com they are a sponsor here and I have heard good things about them.
You will play with the loud pedal a lot more, so the MPG will drop. When you get used to it and keep your foot out of it the MPG will go up. More power and shifts will be quicker if you elect to get #2 or #3 shifts. You can also change when the Torque Converter lock up happens, and I like that part.
