Hey all -

I've got an 05 Coupe - Auto and am putting the Evo 3.91 gears in - do I have to re-calibrate the speedo on this model year?

Thanks for your guidence...

DOnt know about the 05 , but I put 3.5 gears in my AT5 and it didnt change anything . Was told the speed sensors are on the drive axels , not in the rear end . I did get CEL for a while [17xx ] for the speed sensors , but hasnt come back for over 1,000 miles
