I was just wondering if I do a P-pump swap will I still be able to adjust for my tire size on the speedo with a Smarty?
 
Yes, but its more cost effective to sell the smarty and have the dealer adjust the tire size.

But you can tell people you have a Smarty on your p-pump engine.
 
That's BS.

All they need is the revolutions pr mile and your set.

Sounds like a lazy dealer to me.

Well I've tried the dealer before and I was told by them that they couldn't adjust for a 35" tire

As I recall, the DRBIII has predetermined tires and sizes in it, as well as the rev/mile input. Probably didn't have 35's in the predetermined inputs. Like was said, lazy dealer.
 
Yup. Its in the ABS section of the scan tool. Just need the revolutions per mile of your tires. Had the dealer set mine years ago and its dead on accurate with GPS with my 35" tires.
