| My brother runs 37's on his 04 and at 60 (truck speedo) he's actually going about 70-71, we corrected it with my EFI Live and it started throwing the ABS Light. There wasn't anything we could do to fix it except put it back to stock speedo settings. I think that the tires were just so big the abs didn't know what to do (out of parameters???). I think there are other boxes that will correct it but I couldn't with EFI Live.
