Losing pressure won't keep your engine from reaching normal operating temperature. What it will do, though, is lower the boiling point of your coolant.

Two weeks ago I installed a 180 hyperteck stat when I realized my heat issue I put a 195 stat in from napa. I did not test it befor install.
And about the leak idea. If I had a leak it would still build some pressure maybe more then normal do to an over heat issue do to coolant leak. It basically seems like this thing is running too cold.
Is it possible that do to the new pump stat and coolant that the cooling system is just working too well?
I'm going to flush the heater core and put a new 16lb cap on tomorrow and report back.
Thanks for the help and input everyone.

I've operated gas and diesel vehicles and other engines in the far north ... 60th parallel ... and if you don't need to shut it down, you don't. Diesel 3/4 and 1-tons idle all night then go to work the next day, because diesels are harder to start in those temps, so you just don't shut them off.
Gas or Diesel, they don't overheat, but they don't go below the "normal hot" spot on the gauge either once warmed up ... maybe a bit if you're going at highway speeds in extreme cold, but not much; just enough to see it on the gauge.
By "extreme cold" we're talking below -35 ... I've worked in temps as low as -47C/52F. The engines heat up to operating and stay pegged at the thermostat temp on the gauge.
So, if you can find 95C (about 195F) on the gauge under those conditions, with plenty of cooling help from mother nature, I wouldn't think it's "normal" to not get the engine up to temp in milder sub-freezing conditions.
That does not mean the heater will work, or will work well, though.
I was able to get some miles outside the city on my truck this weekend and after about 20 minutes she stays at 95C and blows hot air at highway speeds; posted speed here is 110 kmH (about 70 mph) and although we've been having a very mild winter by our standards, we're still taking temps hovering above and below freezing; perhaps 25-40F. After a short while the blower is turned to lowest or off (heater control to full hot) and the truck stays warm.
I wouldn't say it's working perfectly ... most trucks I've owned blow hotter at full blower and full hot temp (this is my first Dodge so I don't have any history to go on; might be normal for all I know) ... but it's adequate.

I really don't think it's possible that the cooling system is working "too well", at least not at temperatures where a heater has any Earthly Use.

I am running a 180 stat (with hemifever tune) and after mine warms up, it will toast you in the cab if heater is set to warmest position.
