It’s off by 3 mph and I’m getting 14.7 mpg at the moment. 

6.2 or 5.3L?  And what load range are your nittos?

The only ones I could find in a standard load are Nitto’s. Anyone find anything different? I don’t really want to run a 10 ply tire. 

I have a 2019 TBoss w/ 265/60-R20 I want to put 2” additional leveling kit on the front and run 295/60-R20 any advice ?

Can be done with trimming. Not sure if you'll need spacers or not, but id recommend not using spacers if you can. Then again, im biased and hate huge offsets.

if the speedometer is off calibration wouldn't the MPG gauge be off as well?

[Dunn]

so math is hard for me but if he's technically going faster than what his speedometer says, does that mean he's traveling further than what his MPG gauge would be calculating making MPGs read lower than actual??

it could be but idk, I just think the computer will be off either way you look at it, will need to be recalibrated

Is that recalibration something you can have the dealership do?

[MTBR]

Dealerships are not recalibrating from what I am gathering. There is one thread about a user having issues with the Hypertech Programmer.

 

Anybody get the GM INLINE SPEEDOMETER CALIBRATOR (19-20 1500 / 2020 2500 HD) on Rough Country's website?

 

Can anybody else provide their feedback on how they recalibrated?

My friend just put 35x12.50R18 BFG KO2 (34.50x12.50R20) tires on her stock 18” wheels with no lift or leveling kit yet with very little to no tire rub.

Just picked up my Custom TB 2 weeks ago and this is the look I want.

Anyone happen to know the wheel specs on the stock 18s?  Trying to track down weight, backspace and offset but can't seem to find the info anywhere.
