custom PCM tuning. Find a tuner in your area and he can put a good tune on your car and have the speedometer fixed and have it running better at the same time.

A cheaper alternative would be a hand held programmer, but you're just plain better off with a custom tune

ditto... the speedo needs to be calibrated after a gear swap. you will also be putting more miles on the vehicle then your mileage really says

A tuner does not need to tune the motor to adjust your speedometer. Just look for a tuner near you!

correct. BUT, he's going to have to use the same amount of credits on his tuning software, so he's probably going to charge about the same price either way, so might as well just go ahead and get a custom tune while you're at it

Currect on the credits part! But out here they will charge you $100 to adjust the speedometer as thats what i beleive it cost them to buy the credits per car.... But it will go toward your tune later.

So if a tune is $400, It will only be $300 after.
