I think your pressures might be a bit low... 167 -173 hot seems about 15 degrees too low, as does 23 psi out of the tyre warmer.. Try putting 2 psi into the rear tyre and see if that helps. I know that Dunlop specifies 23 psi, but try 25 psi and see if it helps.
Dunlop does say that the tyre yo are using may be susceptible to cold tearing on occasion:
Track Data: Barber, Road Atlanta, Talladega, Blackhawk, Road America, Mid Ohio, Homestead, Grattan, Loudon, Nashville, Summit, Beaver Run, VIR - Front 6704 or 6680 work well. The 6680 may be a bit more consistent and last longer on hot days. Grip is about the same for both unless real hot and the 6680 is better. 6671 would be used for endurance if not too cold. Rear 6714 or 7704 or 6680 all work well at these tracks. If the outside temp is less than 70 degrees, the 7614 may be more likely to cold tear. 7614 is best used in hot temps and it will not last as long as the other compounds but will grip very well. 6680 is the most durable and consistent of the compounds. It is not far off the grip of 7704 but has better durability and less susceptible to cold tearing.
