About us
Our business was founded in 2013 by current owner and car enthusiast Sean McGarry. We focus our efforts on ECU Remapping and strive to provide the best and most comprehensive service available. Our initial roots began back in 2010 when Sean started tuning vehicles as a hobby. Since then SM Tuning has grown from strength to strength tuning over 5,000 vehicles directly and for our global dealer network. We have a UK nationwide mobile tuning service and rolling road / dyno tuning based in Stevenage, Hertfordshire. Our vast array of tuning tools gives us great scope and ability to support most makes and models of vehicle on the market today. This can range from cars, bikes, vans, trucks etc. Our reviews echo our 5 star services we offer. Get in touch today to see how we can help you!
