And before anyone chimes in about "use the Dallas Mustang one instead," they are the same friggen thing, the Brothers is cheaper, and the DM are the brand that had the bad batch of speedcals, not Brothers.
yes it will. you can correct it by installing a Speedcal (available from dallas mustang), that will run you about $99 depending on if you buy it new or second hand.
im putting mine on tmw. Just had my 3.73's put in thursday, on the freeway at about 60-65 it says 85 or so i think. I have the borthers speedcal, got it for $50 shipped used.
