Speedo recalibration

so i went from stock to 285s to now 305s. the speedo is well over 10% off (and ill check it with my gps), and im wondering if there is any way to recalibrate that speedo w/o buying a 600 buck smarty or other ecu programmer and without regearing (i love my highway rpms with the 35's and there is NO lack of power)

is there a speedo gear somewhere in the drivetrain like on my jeep? it has an easily interchangeable 30 dollar ring gear off of the tcase output shaft

You can go to the dealer and have it reflashed maybe. I am thinking though the dealer can only reflash up to 285 size.

I'm pretty sure Superchips does the recalibration for bigger tires
