I usually have air in the heater core that I can get out with a trip around the block, but no problems other than that. Prob just my heater core lines being too high up behind the head.

Those funnles are great for shop work. Put it on, fill it up, idle the car until it burps itself happy. Usually that's an easy way to go enjoy a coffee when you have that thing on and going

With temp reading in the outlet pipe, I don't think you're far off or wrong at all. Gotta remember the OEM temp reading is 'pre' engine, so it will naturally read a lower than post engine once it's up and going as it's where chilled water from the thermostat enters. The highway speed difference is probbaly more due to bumper type than anything, as the other numbers look spot on for a post head reading.

I personally trust my water temp post head more than anything (I've got a similar product). To see the occasional 210/215 on a track day in July never worries me as I know it's about to get cooled down in the radiator
