Maximum PSI was formed in 2007 by a pair of like-minded racers and enthusiasts. Since then we have grown in size, and narrowed in scope. Currently our focus is almost entirely on BMW forced induction, however our goals have not changed: To provide the highest quality products and services, and to maintain a flawless record with customer satisfaction. We also strongly believe in the race what you sell concept, and we durability test all of our products on the street and track. Maximum PSI and Bimmer Clinic joined forces in February 2016 to create a BMW powerhouse that specializes in service, performance, and repair.
