OK, I installed the 160 ts and on the Xpressway the car runs 20degrees cooler at 176 or so, in traffic sitting around, it will get up to around 200 to 210, and this is without the fans on or reprogrammed. So far so good.

Once it gets up to 200 degrees, will it drop back down to 176 when you get back out into an open stretch of road?

I've noticed with my C5Z (with a stock thermostat) will tend to hover around 186 or so with open road driving, but when I get into traffic, it will jump up to as much as 220 or so. Then when I get back out of town, even on the open road with no slowing, it never seems to drop below 196 degrees again.

If I can find the time, I want to set up my HPtuners to capture temp data and do a "before and after" when I get a 160 degree ts myself. Figure I should get the radiator flushed anyway and this would be a good time to try that out.

That's sounds about right,You shouldn't have no problems with that.Did you flush your antifrezze at that time?Or just refill it?
