I agree, I like the fact that you can use it to monitor gauges. I'm a road-course guy so the shift light will come in handy too.
My only complaint about the state of the industry is that so far no one is able, or perhaps unwilling to tune cam phasing. If people are happy with the modest gains they're getting now, wait till you can dial in the cams. In this one area the import tuners have the domestic market beat in that they've been tuning variable systems for many years. I can't wait till things catch up!
