Spencer did a great job on my tuning, fixed an issue I had with the fuel system after it was deleted from the dealership and even came to Bonney Lake to check my truck out! This place is like no other. Btw...I was quoted $12,000-$15,000 to fix my fuel system from performance diesel and Spencer simply unplugged my smog unit that my employee accidentally plugged back in! That was the problem...not $15,000 for a new fuel system!

Spencer and Matt really know there stuff and take pride in there work, great at explaining and educating about the work being done or future upgrades and potential problems to prepare for down the road. They will always have our business thanks guys

Drop off parts to them daily. Alwaies working when I go in the shop. The counter gal is very helpful and has worked on and in the auto industry 4 approximately 10 years that I know of

Respectful, educated, hard working people that are dedicated to the job at hand. Brought my obs 7.3 in and I’ll come back to addiction diesel for any future repairs or modifications.

Spencer and Matt are good guys that I trust, which is hard to find in a mechanic. Started going there because they were easy to talk to and knew their stuff. Keep going there because they are honest and take care of my 6.0 liter.

This is a great shop!! From my first experience with Danny at the counter to the discussions with guys in the shop. I’m sorry I didn’t get their names, but I’ll be back again. I’ve been trying to find a good shop to work on my Duramax and I finally found them. This is the shop you want that won’t charge you for stuff you just don’t need. I had a bad glow plug and rather than risk changing them all (which. Plus go really bad) they swapped out the bad one for an extremely reasonable price. Oil changes to tuning—these folks know what they’re doing.

All I can tell you is... absolutely amazing! Best place to work with! They are genuinely there for there customers and understand every situation. There open line of communication is outstanding! I wont take my truck anywhere else! I will definitely refer my friends and family! Oh, and bring a snack for Diesel the dog! 😁

I was looking for a place to take my 06 6.0 Powerstroke. Through positive word of mouth, I reached out. I am very happy I did. They got me right in and confirmed what I needed. Spencer explained everything and broke down pricing while keeping me updated along the way. The work was precise and clean. Great job to the crew. I highly recommend you give these guys a try. You wont be disappointed. Dont forget a treat for the shop dog!

Great service and guys. Wont take my truck anywhere but addiction diesel!

Their diesel work maybe ok but their word is junk! Was told to bring back truck for an oil change for all the parts they used of mine for the repair. When I did they wanted 200 more bucks after $14,ooo Ill look around for I use them again

Best mechanics ever

Very helpful and amazing customer service

This guy knows his coal!!!
