The speedomitor was off about 5 mph. but with speedo out, so is the shift points, so the truck used more gas and had no get up and go. Now that the speedo is in cal again I have the power back and it is shifting points right.

 

I went from 245 to 265, and recal'd at the dealer- $90. Don't like the way it handles or dives with the 265's.
If I go back to 245 the OEM size, should I recal right away or canI wait awhile? I drive about20 miles a day and funds are tight right now to recal for 245's or buy a programmer.
Anybody in South Jersey have a Programmer or a Superchips Tirepaq programmer that would do it for $20?
