This is something I would hope dodge and your ram dealer service would know about however--if that's the case, the swap should have gone hand in hand with a swap to a different computer system.
This is true, they are quite complex and do adjust to different driving habits... but that part of the computer would be completely separate from where you would adjust numbers such as gear ratios, tire size, ect.... Like I said before, I can understand not being able to adjust the gear ratio (even though a Bully Dog tuner can do it) but they should be able to adjust the tire size no problem. So either way the problem should be corrected.
