I had a ej255 motor built by Turnin Concepts and was recommended to Circuit motorsports by them as a trusted installer that is "close" to me. From the beginning Tristan was hugely helpful and always got back to me in a timely manner. He was very flexible in working within my budget while also making the build as reliable as possible. The base map they dialed in for the break-in process drove super smoothly. You never woulda known there was a rotated big turbo set up in it wit
