2005 Ford F150 5.4 Speedometer Correction

Post by ecl351 »

I am not able to correct my speedometer by changing the tire revs and gear ratio on my T1000. The T1000 seams to take the corrections but my speedo is off by 4 mph no matter what ratio or tire revs I put in. This is for a 2005 Ford F150 5.4
