160 degree thermostat

A quick question for you guys, I have a 96 yukon with the 5.7, I recently installed the hypertech power programmer, and also bought the hypertech 160 degree thermostat. I have heard a few different things on running a low degree thermostat like that. Some say I want have a problem, others say the cold start (choke on newer models) will never turn off because it will never get warm enough. Just wondering if any of you have run a 160 in this type of truck and if it is ok to do so? If you have any info on this please let me know.
thanks
