Hi guys I just put in 410's in my 04 mustang gt 5 speed. I have an excaliber 2 tunner, will this fix my speedometer problem? I know it will fix the auto transmissions but i did not know about the manual. if it does not fix it, a speedcal will work. Correct?

 

im not sure so dont take my word for it but it should as long as youre speedometer runs off youre PCM . . .i know with older models you need some plastic gear. . but i think stop using them in around 1998 hope i helped

 

...I've been told you can correct with the Xcal2, I just have not done that yet!

 

Thanks for the input guys. My sct dealer just emailed me back and confirmed that you can fix the speedo prob with the excal. Thanks again guys.

 

I need to get an Xcal to fix mine also. I like your rims
