Auto Produce Boss is renown throughout the Japanese tuning world for our Rom tuning. We use a combination of street tuning and our 4 wheel drive Dynapack Dynamometer to achieve the best end product for the customer. Aside from out LAP tune computers we also tune: HKS VPro, Apexi PowerFC, Motec, Tomei Reytec and Trust E-manage.

Auto Produce Boss is always incorporating cutting edge technology in order to meet the demands of the "Street Car" world; where "Speed" is achieved from the culmination of consistent and safe performance. In this level of motorsports, 1/1000th of a second is the determining factor of competition.

We strive to be the "Professional Force" who supports the motorsport and tuning activities of the leaders of the street car world, the automotive manufacturers and aftermarket manufacturers.

In the racing world, we have provided CPUs and exhaust manifolds to various JGTC teams. We have also provided many N1 endurance teams with our CPUs, resulting in numerous records. With street cars, we have set many record setting times at time attack events held by different media at Tsukuba Circuit.

More recently, we have been involved in the preparation of vehicles for the All Japan Professional Drift Series(D1) and have gained the trust and respect from many top level drivers.

By placing ourselves in the "Street Car" world through parts development, we have become well versed in CPU tuning during a time where automotive electronic parts are making continuous advancements. Keeping CPU tuning at the heart, we also strive in parts development such as exhaust components, providing a constant link between race vehicles and the street cars.

The knowledge and skills acquired through our activities is applied to the services of other parts manufacturers in the form of research and development for suspension systems(ie. shocks, springs, pillow ball control arms etc.)

From motorsports to the street and the street to motorsports. We are constantly active to providing a link between the street and motorsports. All of the knowledge acquired through our activities is applied to each and every product we develop.

We are constantly striving to produce parts by looking at the car as a whole; by clarifying the purpose of each part and not looking at it on an individual basis.
