To Reprogram PSOM or Not To Program...
Hello All,
I have a 1993 4.9l with a M5OD Manual and my tires are no longer stock. My question is, does the computer in this era of EFI require accurate measures of road speed or does it just get by with engine RPM? If it does require accurate speed input I guess I will reprogram the Speedo as my 33's put it out by about 14%.
Thx.
