over the years, xs engineering has groomed itself to be what we feel a full-service tuning shop should be. we offer professional engine and chassis tuning, complete vehicle preparation, fabrication, and light manufacturing services. our r&d department now boasts both the ubiquitous 2wd 1200hp dynojet 248 chassis dynamometer, as well as a 4wd 1500hp dts 9500 chassis dynamometer.
