Definitely cut that mixture of pure anitfreeze! That's probably your biggest problem. 50/50, or 60/40 are decent ratios. Mix it for your climate, most 50/50's will only gel at -34C. A 60/40 will take you down to -50C. If it doesn't get too cold, go 40/60, safe to aprox -28C or so.
Referring to flow, water flows easier than Glycol, it is thinner. Better flow may promote more heat into the heater core.

like said above cut it to 60/40 max
only other thing I can think is maybe the heater core has an airlock in it....after you cut the mix let the truck idle with the heater on and the hose that feeds the core pinch it with yer hand several times to create a surge and that may get the airlock out

My 01 I bought back in December had that same problem. Truck has 200k on it. Had the heater core changed out as it was plugged and starting to leak. Also just replaced the ballast resistor for the heater motor. Now all works fine. Will have the A/C checked in the next couple weeks to make sure it is as cold as it should be.
