160 Thermostat Can I use a 160 thermostat and adjust my fan temps and be ok? Or will I stay in open loop because the pcm will think the motor has not reached operating temp. Thanks

I'm by far not the expert on this stuff, but I've never heard of anybody throwing a code after putting in a 160 thermostat. I put one in, and I never reset my fans, and I haven't throw any codes (I plan on resetting them thought).
I've read that with a 160 thermostat the engine temp runs about 175, the stock stat is 180, and the engine runs about 195.
Before the needle was always half-on half-off the 210 line on the gauge, after I put in the 160 stat it was just off the gauge. I did put in an aftermarket gauge and it runs about 175 - 180.

the problem I had was I trusted the stock gauge, I now have a 160 with two holes drilled in it. So it is a little colder. If you dont alter the fan temp it doesnt run much cooler than the stock stat.
You roll into open loop when ECT > 100F. So no worries on the
'stat unless it's extremely cold out and there is a lot of base
bypass (thermostat never fully closed). Which is not the case
on the Hype-Tech 160 as far as I've seen on my vehicle. With
drilled holes you might get there in arctic conditions but that's
not a problem down here in the swamp. I have one 3/32 hole
drilled in mine just for luck & bubbles.
