Fabrication & Service Division Closed
After nearly 10 years of high performance service, projects and custom fabrication the PSI Tuning Fabrication & Service division has been closed effective August 30th 2011. This decision was made in order to concentrate on ECU reverse engineering, tuning and controller design. We appreciate the years of patronage from clients and all of the exciting projects we have been allowed to produce.
