Hello @
JOGAN
I will try to answer what I can.
I would think they can trace if they look at the ecm and see how many times it was flashed but I don’t have a definite answer for that.
So as far as my experience with the MM3 tuner I can tell you it’s awesome and I love it.
I have a 16’ with the 68RFE trans.
Currently have the emissions tuning on it and run a 80hp tune with a average of 18 mpg around town and 25 on freeway with 35” tires. Have 45k miles on it running the tunes and no problems. And 60k miles on truck.
MM3 is a blank tuner so you will have to have custom tunes for it which is worth it anyway vs a box tune in my opinion.
It is very easy to install and flash ecm. Touch of a button and any tune you want is sent and just like that more HP.
I am in process of deleting my truck now. Had DRD do the new tunes for it.
New sd card and reprogram the ecm. Change out exhaust and either leave the egr in place or get the block off plates and it’s that easy for delete if you want.
Depending on what you do for emissions tuning or delete will depend on what tunes you get. 4 tunes Up 120hp with emissions or 6 tunes up to 200hp deleted if I remember right.
Also the sound tunes if you want. Lope, whistle and 12 valve.
It is all in the DRD website.
Also a brother in Christ is a plus so it says a lot to me also.
Hope the info helps a bit for you
