Your light to medium duty diesel headquarters in Grand Rapids, MI Service, Repair, and Performance for Duramax, Cummins, and Powerstroke
From out-of-the-box downloads to custom tuning this is our favorite part of the job. Nowhere else in the automotive industry can you get so much for so little. Programming choice is critical when shopping for horsepower: what makes one truck rip will be barely noticeable on another. If there is a tuner on the market we have played with it. We know what’s hot and what’s not for your specific truck. Let us know what you want out of your truck and we will get you there.
From a check engine light to your vehicle not starting we can help. With our state-of- the-art equipment and technician experience we are better equipped to diagnose your vehicle more accurately the first time.
For everything you ask your vehicle to do, it really deserves a bit in return. Come see us for oil changes that include such things as fluid top offs, driveline inspections, tire rotations, and more. Most shops pay their techs too little and don’t give them enough time to check things over to the degree required. Leave our shop with confidence that your differential fluid
is topped off and tie-rods actually got
Along with our tuning services we provide and install most of the leading performance produets. These modifications, when paired properly, produce some of the most radical
vehicles on the road today. At Dieseltec we sweat horsepower and bleed torque, try not to slip when you come by to chat about that new exhaust system custom set of injectors!
While we have one of the most affordable shop labor rates around, that’s not what we hang our hat on. We take pride in what we do and back it up with some of the most no- nonsense warranties available. We may focus on diesel but there is no need to travel to multiple specialty shops. If the manufacturer put it between the bumpers we are on it.
Is your Duramax smoking? Does your Powerstroke not start when it’s hot? How about your Cummins, is it putting down the power it could be?
We are a full service light to medium duty diesel repair and performance shop. Unlike the repair shop that doesn’t understand why you need a 5″ exhaust or a performance shop that doesn’t know how to fix your truck, we do them both and do them well.
We are a specialty shop. Can we fix your gas car when running rough? Sure, but if you own a diesel pick-up and need to get it back on the road quick or to go down the road quicker, you’ve found the right place.
