4:10 in 2000 lightning

I wantt to put a 4:10 in my 2000 lightning. Anyone know how to deal with the speedometer error ? Thanks.

I think you have to stick with a custom chip to compensate...I don't think the DMP speedcal or Abott ERA will work with the auto tranny(I could be very wrong on that one tho)

Many are running 4.10s and yes you will need a chip to correct it. You do have a chip:dw: if not why not:rolling:
