Is it just me.....I set the fuel computer prior to flight, it reads the proper volume of fuel, its shows the fuel burn, but the fuel on board never decreases......what am I doing wrong?

Really enjoying the airplane and apologies in advance as I'm about to geek out on your thread. I'm sure this isn't easy to model but as a real world T310R owner with time in the 414, it would be amazing to work on the engine performance modeling to accurately reflect how these turbo charged engines behave at different mixture settings. Most owners operate these airplanes at or near top of the green with the mixtures full forward throughout the climb for power and cooling. In a turbo charged engine, regardless of the altitude, the power output/ fuel flow at any given combination of power, rpm and mixture setting is the same ie. there should not be a degradation in power or loss of fuel flow during the climb due to a lack of leaning because the turbo is maintaining the same air density in the engine all the way up to critical altitude at which point you will see drops in MP but only due to the limitations of the turbo. In the sim I noted a drop in power during a climb to 10,000 feet even though my MP and RPM were constant and noticed the fuel flow had dropped to 3 GPH per side. Once i leaned the engines the fuel flow actually increased as did the obvious power output. In actuality the turbocharged engine is in essence a closed system so the engines don't care about changes in ambient pressure as they're maintaining their own atmosphere via the tubor charger. Along those same lines, when leaning the engines in cruise, you shouldn't see an increase in fuel flow as you lean, any decrease in mixture setting is going to produce a corresponding decrease in FF just by it's nature. You will increase power as the mixture gets closer to a max power ratio but the FF will always be decreasing on its way to that point and continue to decrease as you reach peak EGT/TIT and then transition to lean of peak, which is where I operate the T310R. Modeling lean of peak at 16.5-18.5 GPH and 65% ish power would be awesome as well as that's how you get best cooling and range out of these engines in the real world. Again apologies for the geek sesh and hopefully I'm not duplicating others comments that have already been made or issues you've already addressed. Keep up the great work!
