Ever wonder why your newest air intake, cylinder head or exhaust system isn’t giving you as big a performance boost as you were promised? It’s easy to think that part is defective or was just marketed well. But it could be that your engine isn’t tuned to take advantage of it. Every engine comes with factory settings and sensors that are – to put it nicely – “safe”. And while casual drivers will do just fine with these safe settings, if you’re looking to compete with the big boys, a flash system tune-up will help you get an edge.

Modern Automotive Performance offers a variety of engine management and tuning components to help you unlock the true potential of your engine. We have the best devices and accessories from AEM performance tuning, Cobb Tuning, Diablosport and more. Their handheld engine management systems use EFI tuning technology to upload new settings, optimizing your engine for performance, fuel economy and even towing. A number of pre-programmed tunings are included, and you can also create your own. These devices also have built-in diagnostic software, allowing you to check error codes and identify potential problems.

Make tuning even easier with computer software such as Advantage III Pro Racer. This allows you to create custom settings from the comfort of your laptop, than transfer them to your vehicle. If you’re focused on tracking vehicle performance, make sure that information is accurate with our replacement sensors and sensor cables. You’ll receive precise data for everything from oil pressure to the boost levels from your new Evo 8 turbo kit 6766, and you can read that information easily on wideband gauges with bright LED light displays.

Whether you’re looking for Chevy C5 Corvette tuning software or a Ford Mustang engine management system, you can find it at MAP. You don’t always need to install or rebuild big-ticket parts – even factory stock engines can benefit from EFI tuning. Maybe you can’t tune a fish, but with free shipping on most tuners and our expert technicians readily available, you can certainly tune your car.
