I just purchased an 05 SRT10 (6 speed). On the way home, I immediately noticed the speedo is reading fast by approx. 10 mph. The truck has a K&N setup and supposedly has had a tune done. There are no other mods that I'm aware of and I don't think the rear gear has been changed. Shows approx. 1500 RPM at a corrected 70 mph (I followed another car to verify the error).
I'd appreciate some input on how to correct this. I've no problem putting the tune back to stock, providing the K&N can be used with a stock tune.
Some input would be much appreciated.
