Thinking about tuning or upgrading your truck? Here are the answers to the questions we hear most. Not sure what’s right for you? Tell us how you use your truck and we’ll steer you in the right direction.
A tune adjusts the calibrations in your truck’s engine and transmission computers: fueling, injection timing, boost and shift points. The factory settings are a compromise built for every possible owner. A good tune sets them up for how you use your truck.
On modern diesels, emissions-on tuning commonly adds somewhere around 50–150 horsepower and 100–300 lb-ft of torque, depending on the platform, model year and supporting parts. We’ll tell you what’s realistic for your truck before you spend a dime.
Many owners see roughly 1–3 mpg better, mostly on the highway and when not towing. A heavy right foot, big tires or a heavy trailer will eat into that. Results vary from truck to truck, and we’ll be straight with you about what to expect.
Yes, it’s one of the best reasons to tune. A tow-focused tune can firm up shifts, hold gears better on hills and help keep exhaust temperatures in check, so the truck pulls with less strain.
A sensible tune stays well within what your truck can handle. Problems usually come from adding more power than the drivetrain was built for, especially the transmission, or skipping supporting parts. That’s exactly why we plan every build.
Most trucks are best served by protecting what you have first: fuel system protection and gauges to keep an eye on boost, exhaust temperature and transmission temperature. Then a tune, then bigger upgrades as your goals grow. We’ll lay out the steps in the right order for your truck.
In most cases, yes. Your factory calibration can be saved before we tune, so it can be put back later if you sell the truck or take it to the dealer.
Modifications can affect warranty coverage on related parts. Under the federal Magnuson-Moss Warranty Act, a manufacturer generally has to show that a modification caused a failure to deny that repair, but tunes can be detected and disputes do happen. We’ll walk through the risks with you before any work starts.
Not always. Most stock transmissions handle a mild to moderate tune just fine, and transmission tuning alone can make shifts firmer and reduce slipping. The transmission is usually the first weak link once you go after big power or tow heavy, so we’ll tell you honestly where your truck’s limit is before you get there.
Every truck and every build is different. You’ll get a clear quote before any work begins, with no surprises.
No pressure, no upsell. Tell us what you tow, how you drive and what you want out of your truck. We’ll steer you in the right direction.
