I'm a new Roxor owner and really want to unleash the horsepower and torque and remove the speed limiter. I've seen the Diesel Freak and Grit Shift websites, and I'm sure there are others. Which companie's tune is best?

Call diesel freak they will get you set up with a custom tune that is exactly to your specs and they can adjust it as you build out your roxor. They adjust for tire size, turbo size, grid heater timing/trigger temp, and can even adjust the idle down to get you a slower crawl speed.

What year Roxor do you have?
Good question. the new HD roxors have the new bosch ECU and are locked down tight! I was at dinner the other night with the design team from Mahindra and they didn't think anyone was going to crack it for some time.

I have had 2 tuned by Diesel Freak and they are top notch. Wade has put a ton of R&D into these and their tune is well worth the cost. Stage II on stock everything has been great for me. I was just driving it a few mins ago and grin ear to ear every time

2018 for me , just took mine for a ride after the Gilomen tune and the difference was night and day from stock. I'd like to try the other tunes to see if they are worth the extra $$. I guess it would come down to what a guy needs.

I have not had my tune done yet but I have settled on DF as I understand they will adjust the number of seconds, after key is turned on, and always activate the grid heater after the number of seconds elapses. This is critical for me because during the winter, on cold nights, I plug mine in so the Kats in line radiator hose heater keeps it warm. The downside is, the grid heater does not come on on cold start so if you live in cold country and use some kind of a heater, make sure whatever tune you put on it has this feature.
