ESS Performance Products USA Inc.

Just had my 5th BMW tuned by ESS (550i, 435i, X5, M3 and now my M5!)... I can't believe how much smoother the car feels, and how much power it added! Also, dealing with AJ was great as he answered my million questions about BMW tuning and mods... couldn't be happier with the money spent and will continue going there for my future vehicles!

After lots of research, I went with an ESS tune over the JB4 for my 2008 335i and I couldn't be happier. The flash install was super easy and the customer support team answered my emails almost instantly. The flash totally changed the car. After installing the stage 2 flash, when I would mash the accelerator, the front end of the car would lift up like a muscle car. The horsepower gains are REAL. The ESS tune is a must have for an N54 or N55 engines!

I've had ESS Performance products on multiple vehicles over the years. Most recently, I had their flash tune on my F10 M5 and I currently have their supercharger kit on my '16 Mustang GT. Always phenomenal service and great products. Couldn't be happier!

Great customer service and even better products. ESS has been the #1 supplier of BMW supercharger kits and after a trip to their shop, it’s easy to see why. The product quality is simply outstanding.

Chase was awesome. Made sure my answers were fully satisfied before hanging up!
