I have a MM3 on my 2016 Ram 3500 DRW with the ASIN Trans and the guy that sent the tunes to me sucks in all honesty.

Tunes are good and work well BUT I have the ASIN Trans and my check engine light is on Constantly.

(Very annoying)

Is there someone that will sell me just new tunes? Thus far all I can find are people selling the whole deal. I have the 30HP 60HP 130HP and 200HP tunes now and like I said they all work well but the damn Check engine lite is on all the time.

I checked for codes and got a 02 sensor code the 1st time let them know he sent new tunes and I still have a check engine light but not throwing any codes per the MM3 (Strange)

The guy that did the tunes is Some Guy that goes by Fast Tommy.

I got the kit off eBay there company name is Diesel Tuners.

Truck has been threw about 20 Stop starts and still a check engine light has not gone away.

Drives me nuts at night in the dark LOL.

Any help would be great and thank you in advance.
