You’ve invested in your vehicle's performance. Finish the job right by making sure the engine reaches its full potential. No matter how good the tuner, you can’t get live real-time feedback and customized adjustments with a mail order tune. Every car has subtle differences. When you want the best possible performance there is no substitute for an experienced tuner working in the same room as the engine and making adjustments specific to your individual car.

We are Long Island's premier Mustang Performance shop. At Realspeed we treat every vehicle with the care and dedication that we would want for our own car. We have extensive knowledge of Ford electronic engine controls, SCT tuning software, high performance engine design theory and forced induction (supercharging, turbocharging, nitrous). We have the experience to give you the best tune possible. We go the extra mile to make sure your tune comes out right

Realspeed Automotive was founded by Dan Carlson to provide the highest quality parts and customer service to Mustang and Ford Enthusiasts.

Mr. Carlson spent a decade designing parts for Steeda Autosports before forming Realspeed Automotive in 2004.

Racing has always been a passion for Dan, whether it was a little 13 foot boat when he was 10 years old, rallying his friends to take all their cars to the drag strip for a grudge-match, or competing in road races with the Sports Car Club of America.

Today Dan’s Mustang runs the quarter mile in 10.4 @ 132 mph and gets 22 mpg on the highway and 16 mpg around town. It is still driven daily, out-handles most other mustangs on the road, and is used for everything from weekend cruising to picking the kids up from school. All this is accomplished with the help of about a dozen parts that Dan designed himself, and most of those parts are available right here at realspeedautomotive.com.

Realspeed Automotive is located on Long Island, New York. We are dedicated to providing top notch installation for aftermarket parts and custom dyno tuning. We also have a fully stocked warehouse and ship to anywhere in the U.S. and Canada.
