Mutant Diesel Performance Ltd.

Got me in the next day and had my truck back to me within 6 hrs. Def delete on my truck has increased my mileage as well power. We did have a small exhaust leak due to a flange issue but they took the truck back in instantly and made it right within 30 min. I highly recommend these guys!

TROY IS THE MAN. KEEPS HIS WORD ,HONEST, GOOD PRICES. KNOWS WHAT HE IS DOING. THANKS AGAIN TROY.PETE AT ARMAGEDDON DIESEL

Troy appears to be an honest tuner. My company had him program some engines and they run very very nicely. He was very upfront about what he could and couldn't do.

Excellent, I can't say enough good things about this shop.

The service at Mutant Diesel was great! Fixed my truck got a new tuner they really know there stuff. If you have a Dodge diesel this is the place to take your truck.Thanks Troy !

Called these guys back for a potential warranty job. I was met with attitude and a hang up. Very unprofessional, use at your discretion.

Last winter my 2014 EcoDiesel’s DEF pump decided that it was time to quit on me. The pump had already been replaced once, and to have it replaced again was going to cost me an arm and a leg, so I began looking for a shop who could do a DEF delete for me. All the other shops I called at the time either didn’t return my calls, or didn’t sound confident that they could do an EcoDiesel for one reason or another. I called Troy and left a message, and within half a day my truck was dropped off. The service was very fast and I had my truck back within 24 hours. I have had zero problems with it since taking it to Troy after almost 40,000 km’s. I also had him tune it, and it is quite a bit quicker now, while also getting better fuel economy. 7-9 L/100Km from Calgary to Edmonton cruising at 115 Km/hr. I would highly recommend Troy, and if I need anything done with my truck I will definitely be taking it back to him.

Great place
