Odd Speedo Issue
Odd Speedo Issue
I have an XCal2 via BamaChips. 35" BFG KM2s. 3.55 stock rearend.
Well, my electronic display (2004 XLT...holdin the trip reset when I start the vehicle) shows the correct speed on the digital read out. However, my speedo shows approx 10%mph faster than I am going (i.e. speedo shows appox 85, I'm actually going approx 77).
Thoughts? Anyone else ever experienced this? Mechanical problem with the speedo, considering the digital readout is fine?
