Default Speedo help!!

I just bought a new 9in with the 3.89 gears for my 02 Ws6 and got my tuner to retune for the gears but for some reason after the retune my speedometer is still off about 5mph under what it should be(60mph=55mph). Is there a gear that I can change or is everything on my car electronic???

No gears to change.... all is changed in the tune...

Default 3.89s

I went from 3.23s to 3.89s. STS did my tune and it is spot on. Speedo change is based on a percentage of ratio change, not mph. Don't know if you were 3.23 before, but if you were, difference is 20%.

Should have been 3.42's because I have the m6....
