Pretty horrible to be honest. Way too overpriced, and gave me the wrong diagnosis. Charged me over $300 just to tell me that the back left ABS sensor was gone and that was why my ABS light was on. Wanted to charge me another $400 to replace it. Ended up doing it myself (bought a second hand one for $140 and spent a significant amount of time replacing it) only to find it was not the problem and I had wasted all that time and money. Not to mention they pulled my rear vision mirror off the windscreen and did not glue it back on. Sorry but would not recommend or ever go back to any Ultra Tune.
