500 to the wheels or just a few extra horsepower, dial it in with a pro.
Make the most of the time and money you've spent on your project by getting a custom Focus ST/RS tune from the best. We've tuned literally thousands of STs and RSs from completely stock to huge turbo setups with auxiliary fuel systems. We can tune yours, too.

Tune Anywhere, On Your Time
We have a dyno, but remote tuning is the majority of what we do. It's all done at your convenience, wherever you're located.
Power + Reliability
Making the most power/torque is our goal, but not at the risk of failure. Safety and reliability are a big part of our tuning strategy.
No Waiting, Just Tuning
We offer the fastest response times, allowing you to dial in your tune in as fast as a couple days.
Tuning is Critical to Maximizing Your Focus ST/RS Setup
Not only is tuning extremely important with modern EFI systems, but the Focus ST/RS, in particular, has one of the most complex tuning strategies you'll find.
Using the Cobb Tuning AccessPort, we'll calibrate your ECU to make more power and torque while keeping the engine as efficient, reliable, and safe as possible.
If you're here, we know your Focus ST/RS is more than just a daily. You might even be putting a big turbo on and need it tuned ASAP. We'll help you get more power if it's bone stock or we can dial in your new cams, 2.3 stroker, and G30-770 turbo. We're ready for duty.

FAQs
Many customers have different setups and requirements. We've seen just about all of them and can handle almost anything. But here are some commonly asked questions.
Can you tune with ethanol?
Yes. We frequently tune different ethanol blended fuels, mostly E30 (30% ethanol, 70% gas). We can also handle methanol injection, race fuel, auxiliary fueling systems, and even nitrous. We'll give you different maps for the different fuels we're tuning with.
How much boost and power will I make?
Although we usually see similar results with comparable setups, this is truly an impossible question to answer. Generally speaking, stock turbo cars will see as much as 22-23psi of peak boost and about 280whp/360wtq with supporting modifications. With big turbo setups, it's all about the fuel limitations. If you have a stock fuel system, plan on 350-380whp depending on the fuel being used. If you have the right fueling setup, the only limitation is your turbo size and engine strength. We've tuned several 500whp+ cars.
I've heard tuning isn't safe. Is that true?
Tuning by itself is not inherently unsafe. If anything, sometimes it's unsafe NOT to be tuned if you've modified your car. With that said, inexperienced or unqualified tuners can be unsafe, which is why choosing the right one is so important. There are a lot of good tuners out there. We share a space at the top with the best of them.
Can you send a base map for when I install my big turbo?
Yes. This is a common scenario and one we're used to. We have base maps ready to go and can send one within 24 hours of purchase so that once your big turbo is on, you can drive it immediately and begin the tuning process after confirming your car is running smoothly. We can do this for motor break-ins and even stroker setups, too. You start tuning when you're ready.
Reviews
"This was the easiest and fastest process by far. The responses were fast and my tune was completed with in a week. The car is so much better on gas and power, couldn't be happier."
Jonathan, Online Review
"Currently working through tune revisions with Alan now. I'm chose a 93 octane and an E30 dual fuel. Thus is only the 3rd revision of 93 octane, and I'm very impressed with how much the car wakes up with each revision. I'm excited to move on to the E30. Alan has answered multiple questions I've come across, in regards to what different gauge readings mean and what might effect the results.
Highly recommend an EdgeAutosport tune over the Cobb OTS tunes."

"Alan has done a very well job at guiding me through the tuning process for a big turbo and fuel pump, my ST is making its power goals and running as well as can be!"
