The best shop in Missoula! Non vgt swapped my 6.0 powerstroke and gained me a ton of horsepower and I’ve never had a single issue! I didn’t mind the slight wait because of the exceptional work! Super kind crew and great people to know!

Josh and Luke were great ppl, they had my truck in the shop immediately got it serviced looked over , suggested things that will be needed to be done in the near future and back out the door as quickly as possible. Highly recommend them for dependable and honest work on your diesel.
