A few of the cars that have come through Eurocharged Atlanta.
“I had an outstanding experience with Eurocharged in Atlanta tuning my Ferrari SF90 (Stage 1). Akeem made the entire process incredibly smooth and straightforward from start to finish—professional, knowledgeable, and easy to work with. This is actually my second tune with Eurocharged, and they continue to exceed expectations. My first experience was with my Mercedes-Benz GT 63, and I was just as impressed then as I am now. Their products deliver real performance gains, and you can feel the difference immediately. If you’re considering a tune and want a team that knows what they’re doing and stands behind their work, I highly recommend Eurocharged. I’ll definitely be coming back again.”
“Akeem has done nothing short of outstanding services on our Audi and Mercedes. Hands down one of the most honest mechanics I’ve came across, he tells you exactly what your car needs and gets it done in an efficient manner. I trust him fully with any of our cars. I would most definitely recommend if anyone is looking for a mechanic in the area to hit up Akeem for your car needs.”
“Akeem as all the reviews state is an amazing tuner! If I could give this shop more starts I would. My TCU tune has given my 550 amazing acceleration. Everyone looking to tune their ECU and TCU this should be your first stop in the Georgia area for Euro tuning.”

Short guides that answer the questions we hear most, before you book.
Your car has a computer that decides how the engine runs. Tuning means carefully changing its instructions so the car drives the way you want.
5 min readStages are a simple way to describe how far a car has been modified. Here is what each one usually means and who it is for.
5 min readYour gearbox has its own computer. Tuning it changes how quickly and firmly the car shifts, and lets it handle the extra power from an engine tune.
4 min readE85 is a high-ethanol fuel that can support more power on the right car. It also has real downsides, so here is the honest picture.
5 min readStill unsure about something? Call the shop at (470) 359-4197 and ask.
A tune can affect powertrain warranty coverage. We are upfront about it: we will tell you what is at risk on your specific platform, and on most vehicles we can return the car to a stock file if you need it back to factory calibration for a dealer visit.
That is the whole point of a custom calibration. We tune around your hardware, fuel and driving conditions with safe knock, boost and temperature targets, rather than loading a generic file written for someone else's car.
Most ECU-only tunes are a same-day appointment. Stage kits and hardware installs typically run one to three days depending on parts availability. We confirm the timeline before you book.
Tune pricing depends on platform and stage, so we quote per vehicle. Our published shop labor rate is $180/hr. Send your car details through the form and we come back with a real number.
Yes. Modified cars, other shops' tunes and problem builds are a large part of what we do. Tell us what has been done to it in the form and we will pick it up from there.
