Life is a learning process.
The mistakes we make teach us valuable lessons. Some more costly than others, but a lesson learned nonetheless.
I made the costly mistake of buying a Raceme Ultra with loaded box tunes, as opposed to just buying a blank MM3 or Raceme and paying for the magical work of Ray and Double R Diesel.
The difference is night and day y'all, and you actually have real customer support to go along with it.
Don't ever waste money on box tunes.
Do it right the first time!
Thank you Ray, you have given me a warm and fuzzy feeling knowing my truck is tuned to the best it can be!!!
