Customer Reviews

Trusted by Local Diesel Truck Owners

5.0 — Locally Trusted Diesel Experts
DFI Performance diagnosed a fuel system issue that two other shops missed. Honest, upfront pricing and my truck runs better than ever. These guys know diesel.

Mike R.

2018 Ram 3500 Cummins

Had my turbo go out on a Monday they had me back on the road by Thursday. Fast turnaround, fair price, and they kept me updated the whole time. Highly recommend.

Jason T.

2021 Chevy Silverado Duramax

Best diesel shop in Northwest Oregon. They did a full engine overhaul on my work truck and the results speak for themselves. Reliable, affordable, and diesel experts.

Dave S.

2016 Ford F-350 Powerstroke

Brought my truck in for a performance tune and towing upgrade. The difference is night and day. Power is up, fuel economy improved, and it tows my 5th wheel.

Chris M.

2019 Ram 2500 Cummins

Great shop, great people. No BS diagnostics and they actually explained what was wrong before touching anything. Will be back for all my diesel maintenance.

Brian K.

2020 GMC Sierra Duramax

I was skeptical at first but they earned my trust. Fixed an injector issue other shops quoted $4k for at a fraction of the cost. Honest work, honest pricing.
