How it works: we plan the build with you, install and tune it on our dyno, and you leave with the dyno sheet.
From our dyno
2014 WRX: custom dyno tune vs. its old e-tune. 30 whp more on 2.5 to 3 psi less boost. 
2011 WRX from Moab, flex fuel tune: 56 hp and 104 lb-ft more on ethanol. 
2001 Prelude: the choppy powerband (red) smoothed out after motor work, parts, and a tune.
You added parts, and the car doesn't feel much different. Or it runs worse. That's because the engine computer still thinks the car is stock. Its settings were made for a stock car at sea level.
Turbo Lab does ECU tuning in Orem. We rewrite those settings for your car and check the result on our AWD Dynojet.

When you need ECU tuning
The ECU is the computer that runs your engine. It decides how much fuel to add, when to fire the spark plugs, and how much boost a turbo makes. ECU tuning changes those settings.
Most modern cars are tuned by flash tuning. We plug into the port under the dash and load new settings into the factory computer. You may need a tune if:
- You added parts, like an intake, exhaust, downpipe, or turbo
- A check engine light came on after a mod
- The car runs rich, hesitates, or feels flat
- You're on an off-the-shelf map and want one made for your car
- You want more power from a stock car
Our ECU tuning process
We tune with COBB, HP Tuners, Uprev, Hondata, KTuner, and Dynojet. We also tune nearly every standalone ECU, like Haltech, AEM, Holley, ACES, Link ECU, ECU Masters, ProEFI, and MegaSquirt. First we look over the engine bay and check the fluid levels. Then we do a baseline pull on the dyno.
Off-the-shelf maps are ready-made tunes for common setups. They're a fair start, but they're often written for sea level and 93 octane. A custom tune is written for your car. We change fuel, timing, and boost one step at a time and log air-fuel and knock on every pull.
Tunes are often sold in stages. Stage 1 is usually a stock car. Stage 2 adds parts like a downpipe. Stage 3 usually means a bigger turbo. Every tuner draws the lines differently, so we tune for your real parts.
ECU tuning cost in Orem
A custom dyno tune usually costs $600 to $1,000. The price depends on the car, the ECU, the parts on it, and the type of tune. Some cars need a tuning device or license bought for them, which adds to the cost. A custom dyno tune on a built car takes more time than a tune for a stock one.

Tested on our dyno, tuned for 91 octane
We tune on our own AWD Dynojet, so every change is tested under load, not guessed. We tune for Orem's 4,700 feet and the 91 octane sold at most Utah stations. If we find a problem during the tune, we stop and call you. Tuned by another shop? We can retune it. Need parts first? We also do turbo kit installation and performance exhaust installation.

ECU tuning questions
Can I go back to the stock tune?
On many cars, yes. Most tuning tools save the stock file so it can be flashed back later.
Is an off-the-shelf map good enough?
It's a fair start on a stock car. But it wasn't written for your parts or 91 octane at 4,700 feet.
Will tuning void my factory warranty?
Not by itself. Under federal law (the Magnuson-Moss Warranty Act), the maker has to show an aftermarket part caused the problem before it can deny a claim. A tune can still make a claim harder, so ask us first.
Will my car pass emissions after a tune?
Utah County requires emissions testing on most cars. Some tunes carry a CARB Executive Order number, which shows they meet emissions rules. Ask us what a tune means for your car before we start.
How long does ECU tuning take?
Most tunes are done the same day.
Can you retune a car another shop tuned?
Yes. We retune cars tuned by other shops, and we work on builds other shops started.
Still running a stock tune?
Call and tell us what you drive and what's on it. We'll tell you what a tune can do and what it costs before we start.
