Last night I tried to set my tune to accept the 3.73 gears I have. My speedo reads 80 MPH and when I pass two construction speed limit readers they say I'm doing 69 MPH. I called Blow by Racing and they told me what to do so I went out to garage and I could not get in to the gear options. I call back and tell them and was told today by mid day I should have it in my e-mail. Fast forward to today 6:00 pm, no e-mail so I call and I do get a hold of John (them guys be working late)lol and he looks it up and my tune already has 3.73's in the tune. So w/ Johns explaining how to find out if they might in fact be 4.10's I go out jack up car, mark drive-line and turn tire 1 revolution and drive shaft makes 4 revolutions so by that little test it seems I have 4.10's not 3.73's. The box says 373N in the P/N so is it a mix up? BBR will be sending me another updated tune for 4.10's and tomorrow @ Mason-Dixon Dragway I should be able to see what mph I trap and Monday on the way to work I will be passing those speed limit readers and we will see what mph numbers are.
Now if these are in fact 4.10's then I will be glad for the mistake in packaging because I love em'.
