Speedometer correction

[pghplumber]

I've got a 2011 gt/cs which I swapped the stock wheels for GT500 wheels, and it seems my speedometer is off by a few MPH now.

I could swear I remember seeing something about how if you change your wheel diameter you could use a tuner to correct the speedo. Is that right, or is that something I dreamed of?

Thanks

i can do that with my sct tuner. diablo and procal tuners have the options too.

Okay great, thank you so much!

Now....does anyone around the Pittsburgh area want to help me out?

Eventually I will just buy a tuner and blah blah blah, but I don't have the funds right now.

I do however have the funds for a six pack for the person that can help me out.

you can't just plug someones tuner in and change it...doesn't work that way. You have to own a tuner yourself and tune your car with that tuner...

Oh, shoot. I didn't think that changing the diameter qualified as a "tune".
Well...I guess I'm stuck until I get some money.

Is there any possibility that the dealer can do this? (for under $50?)

Thanks again.
