Closed Loop is at idle and at cruising only. Startup, decel, and accel
(including WOT) are Open-Loop operation.

Naaah, 180's don't do that. 160's sometimes do, but if they're calibrated
correctly to begin with, I've never noticed them to be a problem. You're
talking "open loop". Mine's in "open loop" a lot anyway. That's what
happens when you drive at WOT...hehehe.

If you change it to a 180 you will lose mileage and maybe not run as good.
The computer will keep running it in "partal choke" thinking it hasent
warmed up yet. That is hp with a performance chip but not stock.
Not even in the summer should you chnage it to a lower temp. the gauge going
up and down is showing that the thermostat is working.
