I have a glow shift 3 in 1 boost egt and fuel pressure. Works good for the most part but sometimes the numbers will jump around. Oh and if you turn the key on and off a few times before start up, wait for the gauge to light up first, otherwise it will confuse the crap out of it and you have to disconnect the positive and reconnect to get it to work right again.
I won't bother with it
And I NEED the pyro for my moose, fuel pressure is always a good idea for troubleshooting or preventing F$&$ ups and boost is for my curiosity. So I can justify buying all three, but the prices hurt
