About Us

At East Coast Supercharging, LSx Performance is not just our business, it is our passion. ECS was founded to fill the void in the LSx performance shops. We strive every day to be the best in the business. ECS celebrated its 20th anniversary in 2021.


From the moment you contact ECS, you’ll find us to be a little different. From our office manager, sales staff to the shop manager and technicians we all own and drive LSx powered vehicles. They are our passion, and this shows in our work.


ECS was founded by Doug Ring & Chris Coriell in 2000 to fulfill a need in the local performance market. Since then, we’ve developed a large number of LSx focused products to help your car go faster, stop quicker, and perform more reliably on the street or racetrack.


We’ve become very well known for our world famous, record setting supercharging systems, but are well versed in all other aspects of LSx Performance. From heads & cam packages to big cube motors, performance parts, drag racing & road race set up, sales, service, we have the experience  to make your driving experience everything you want it to be.
