Ive had a few issues with the max tow series of gauges let alone the boost gauge. They will make it the 1 year till the warranty is up then issues will arise. I had lights fail. Gauges not turn on everytime. Major issues with interference with radios. If you use a CB or a 2 way radio expect the gauges to mess up during a transmission and no they will not help you solve that issue. But for the money they are not junk but they are not the best.
