A year plus with the Mishimoto
Got my Mishi Tstat in today, and took the Ex for a 25 mile drive. With the cruise set at 65 (no real "flat" freeway around me), ECT hovers around 203-205, EOT 208-212. Ambient temp outside is 60*F today. I actually was able to get up to temp without my winter front on the truck. Even with a new 192*F Tstat from the International dealer and my Fia winter front on at 60*F ambient temp, 185*F was my normal operating temp. Got off the freeway and temps dropped to ECT 201, EOT 206 on the surface streets and at stop lights. This would normally give me 170's on my ECT with my new IH Tstat.
Truck sure seems to like the extra 20* of heat, not as sluggish anymore. Put the peddle down, and hold on! Now I'm concerned that towing is going to create too much heat. Guess we'll see.

I've had my Mishi in for a while now and all is well ...200/202 ect 206/208 eot. Tow my 34' tt on a 200 mile trip this past weekend ambient was in the mid to high 80s the humidity nearly the same rolling hills with a couple of long pulls. The ect temp never exceeded 207 and the eot never exceeded 218 and mostly stayed in the 204 ect 214 eot range .......very pleased with the higher tstat all around.

looks like my "high maintenance girlfriend" needs some attention again, my Mishimoto T-stat is running cold. Temps have gotten into the 50's here, and my 200* T-stat it now a 165*. Really too bad, I had hoped it would last longer. Looked at the warranty info, and I lost the receipt and the shipping back and forth is more than the part. Guess I'll have to hop on the Amazon and order another, since the stock T-stat is even worse. I have 3 new stock T-stats that all run at 185, unless you are stopped, then it's closer to 150.

I believe the biggest concern is when you run below 185 the truck is in "cold" mode and injects more fuel in an attempt to warm the truck up faster.
The coolant temp (hundreds of degrees) is also a representation of the engine temp (few thousand) so a change of 10-20 degrees will increase engine temp a lot more than 10-20 and they operate better this way with more power and better MPG. The down side being more heat generates more NOx in the exhaust (bad for the EPA). I'm 80% sure about what I just said in this paragraph.
I was about to buy one because my temps are always around 190-195. however since My wreck and replacing my bumper with a full replacement my temps never fall below 198 on the highway usually around 203-208 right now.
