Coyne Performance LLC

models. E46 M3 and the S54 is my main specialty, rear subframe/RACP repair and reinforcement, VANOS diagnostics/repair, Rod bearing replacement and engine rebuilds. Also any performance installs (Headers/Exhaust, Coilovers, Camshafts) and tuning via TTFS. We have all the specialty tools needed to service the E46/S54 package. I have the latest software for programming and diagnosing all BMWs and many years of BMW-only experience, while also carrying all the same programming and diagnostic equipment carried by the dealer and then some (this includes ISTA-P, ISTA-D, GT-1, and INPA diagnostics) so I can service all BMW from past to present (including F-line cars). I also have a wide range of BMW special tools needed to work on these complex cars. I have the personal attention to detail that only a small BMW repair shop can supply while offering the technical expertise you expect from the BMW dealer.
