Geez... When it rains it pours. I just lost my pyrometer this morning it quit working. So I did my phone shopping at work today since it was slow. Called around and once again my buddy Eric at Vulcan Performance did the best price. I'm just beside myself of taking either ISSPro EV's or ISSPro EV2's. The EV's are all mechanical gauges. Now Eric tells me the EV2's are electronic and using now solid state pressure sensors that are rare to fail. I'm considering on jumping out on a limb and trying the EV2's. What do you all think?

I've been playing with gearing and speed. I find that head down canyon is fine for 5th but actually does slightly better running 4th gear at 55 MPH back home.
