Any methods to test pyrometer?

Hi there, I was wondering if there is any way to test my pyrometer? It seems to be reading lower
than it use to. I am thinking that the new air filter (clean fleetguard) may be letting the engine breath better than the old filter (dirty car quest). Would a new air filter be responsible for a 200 to 300 degree drop in EGT at highway speed? Before, cruising at 70 mph EGT = 600 to 800 and now at the same speed on the same road EGT = 300 to 500. I know outside air temp will have some bearing on this. If the air filter is causing this reduced EGT, then thats great but just to be sure can the pryometer be tested with an ohm meter or some other device?

Thanks so much for your time, John.

Forgot to mention that the pyrometer is mounted pre-turbo.

My air filter system is still stock.

I am running fanless now and have been for about a month and was wondering if this might have something to do with lower egt's.

Thanks again, John.
