MM3 Tuner - Adjust Tire Size / Pressure?

**Sowega6.7** · 08-06-2023

I'm new to Cummins diesel, so I'm still learning.

Can the MM3 adjust for tire size and pressure?

Can EFI Live adjust those?

What makes one better than the other? Just trying to decide what is best for me. I have a 2021 2500.

The last diesel I had was an 01 24v.

Kick me in the *** every day to get rid of it.

Thanks for any info, guys.

The difference is the tuners who are doing it and the platform.

MM3, you have a standard monitor to go off of, but you get the best in the business with MM3 Power support and DRD doing the tunning.

EFI, people claim they know what they're doing, which some do, and you get a rough running outcome.

Some EFI tunes run hot, meaning Higher EGT and a lot of smoke.

With DRD, you get the max power by providing safety first.

MM3 is a company that comes with the purchase of the device; there is no other company out there that remotely comes close to the technical support in the industry.

Hopefully, others can throw more input in for you.

I would strongly suggest going with MM3.

Thank you.

It's hard to find info on this topic these days.

I want to make sure I know all I can before I pull the trigger.
