I have a 2000 F-150, I know this is a mustang forums site, but hopefully someone knows an answer. My question is: I have 315/75/16 or 35" tires on the truck. My speedo is electronic, and I know its way off. Is there any Cheap way to correct it
? I don't wanna buy a programmer cause they are expensive, but I got a huge ticket and I need to re calibrate my speedo. Any answers?

 

programmer is the only way to do it unless you have a cop radar you and you compare your speedo to is radar and just remember how much your off all the time. good luck. i have a 04 heritage edition 4.2L 5 speed and i want to get rid of the damn speed governor on it but i cant do that without a programmer so we are both stuck. but you can get more than just speedo calibration with a prog. so its got more than one good use.

 

Many people here have mentioned something called Speed Cal to correct just the speedo.

 

Spped Cal huh? you remember any posts off the top of your head that mention anything about it? gonna try to do a search for the key words.....

 

Found it On dallas mustang's website. thanks to both of you!
