I have not changed anything. This is what I down loaded from my truck.

H0101 SPEED SENSOR PULSE PER KILOMETER 2485
H0103 FINAL DRIVE RATIO 4.10
H0104 TRANS OUTPUT SHAFT REVS/KM 263
H0136 TIRE REVS PER KILOMETER 424
D5061 TRANSFER CASE RATIO 2.7

I had the dealer recalibrate the speedo for 265's a while ago. I can't figure out why my final drive is set to 4.10. Shouldn't it be 3.73?

Sorry, these are Speedo cals.

Its normal, not correct but, all our trucks electronics are like that.

There was a thread on the efilive forum about this :)

It's the number values that concern me. I don't think the 4.10 should be there.

Every stock tune for your truck is set to 4.10. No worries
