speedo parameters
I recently tuned my 2007 NNBS silverado with EFI Live and when adjusting my speedo for my bigger wheels (305/40-22) in the speedometer parameters tab it shows the correct 638 revs per mile after adjusting it. Thing is after tuning its still off 3 miles per hour. Is there any way my ecm isnt saving the changed data?
