IMHO all of those temperature settings (LS and HS) are about 10 degrees too low.its a 1/2mm bigger, snug fit or touch it on a grinder.

All depends on where you are and how much heat you get, personally I love mine and so does my tuner (Johan), the car just status crisp longer and suffers from little to no KR in the tune as the temps never get high enough to worry about. The only real downside I see is that it is possible to throw a code for not having the cat reach operating parameters within the 'correct' timeline... as I have a tuner it takes a few seconds to reset the code, 4 years of 170 and it has happened once, and I spend lots of time up north as well.After searching this more sounds like that 180 stat is more like 184 .. Should I just go with the 170 since its actually a 174? Just adjust temp settings same as 180 but 10deg diff.. So 179ls 189hs? actually read some older posts that you commented in silver06hemic that 185/195 fan settings are ideal for the 170.. That's only 4deg diff over a 180 stat setting of 189/199 ?
I live in SE PA. When I had the 170 t-stat back in February of 2007 I got the P0128 (thermostat rationality) diagnostic trouble code almost every morning on my way to work. Despite being able to clear it with the Predator (on a nearly daily basis it was a drag) I changed to the 180 t-stat, along with running a 6" wide air baffle across the front of the A/C condenser once the overnight air temperatures started to go below freezing to restrict some of the air flow through the radiator.Should I just go with the 170 ..................?
