Haven't used a temp gun for 6 years since I got into the hobby, never needed one. Maybe it could have come in handy in my TRX 2.5 days, but until I learned to tune I haven't ever needed one. Tuning my sound/smoke/performance is your friend. I guess the only reason I'd personally use a gauge is to measure temp during break in to make sure I'm over 210F.

You always poke your head out when someone mentions temp gauges...
