About A|P
Since 1975, Autothority Performance Engineering has been producing cutting edge performance products for the world's most exciting cars. We helped pioneer the E-PROM industry in the mid eighties, and have spent the last
20 plus years expanding and refining our trade. Our products have proven themselves at the 24 Hours of Daytona, the 12 Hours of Sebring, countless SCCA and club races, many quarter mile races, and tens of thousands of morning commutes, in more than 40 countries around the world.
Autothority Performance Engineering operates out of 12,500 square feet of research/ development and office space in
Alexandria, Virginia, just outside of our nation's capital. Our facilities house some of the most advances tuning equipment in the business, and include:
A Superflow Autodyn Chasis Dynamometer
Complete machine and fabrication facilities
Superflow flow bench
Cam Doctor hardware and software
Proprietary Graphics Tuning Software for incredibly precise E-PROM tuning

Autothority Performance Engineering was born from Autothority Inc., the premier independent Porsche performance and repair facility in the Washington D.C. metropolitan area. Autothority Inc. was formed in 1975 by ex-patent attorney and long time racecar enthusiast Al Collins, who decided to turn his hobby into his livelihood.
The advent of electronic engine management in Porsche automobiles provided the spark that gave A.P.E. life. In the early 1980's, Porsche began using reprogrammed E-PROMS (chips as they are often called) in their race engines with surprising results/ After some preliminary viability studies with an industry renowned software engineer, it was realized that this new technology had much broader implications than originally anticipated. Joel Cohen, a young entrepreneur and long time Autothority Inc. customer, who made his mark in the computer boom of the 1980's, was approached to bring this exciting idea to the marketplace.
Now utilizing state-of-the-art chassis dynamometers and data acquisition systems, the notion of proprietary engine tuning software has become reality. By taking advantage of margins built in to E-PROM software to accommodate engine and fuel variations, performance improvements are realized an average of 10% on otherwise unmodified vehicles. And because of the radically different fuel and timing requirements of modified engines, improvements well above 10% are seen. Performance E-PROM's have been designed and produced for virtually all Porsches and BMWs (using Bosch Motronic and
Siemens engine management systems) as well as many Volkswagen, and
Audi vehicles.
In the past year and a half, we have expanded our software tuning applications as well as opened a new high end show room and retail facility. We continue to sell the finest tuning applications for European and Japanese import applications. Our customers now have the opportunity to experience some of the finest technicians in the country installing their new performance products. Our main objective is to have the customer purchase the product from us and have one of our professionals install it. This way we can assure a proper installation and guarantee the consumer will be happy with their product. Too many times customers purchase a product to install themselves and it does not fit or work properly and he/she is dissatisfied. It could be a simple wiring problem or improper installation and the blame tends to fall on the product or retailer. The worst part is that many times you never know about this and you have lost the trust of the customer in that product or all after market products. We want to support our suppliers and guarantee satisfaction of their product by selling quality service and proper installation. At Autothority, our customers can expect to walk in and receive professional, knowledgeable, and courteous service; a must in ultimate customer satisfaction. Our continuing goal is to educate consumers about our products and take the time to explain and show them how they work. |
