I read some guys are running different thermostats and gaining mileage? Is this true? I don't see how it makes a diff, what is the deal? What thermostat are you running?

I haven't heard of a specific one with those abilities - but I have been thinking about getting a replacement for my stock one since it's been 4+ years now.

Won't do anything unless you can program the fan to come on at the lower temperature. On my Corvette it was worth a dyno proven 12 horsepower.Probably good for 5 hp on this engine.It is not difficult to modify the stock thermostat to open at a lower temp.A simple spacer in the 1/8" range will lower opening temp approx. 20 degrees.To make your own fan controller would take a wiring diagram and a few dollars worth of stuff from radio shack.

A new thermostat can be had at almost any auto parts store,there at least four different manufacturers, they all are set for 195 degrees, was unable to locate one set for a lower temp.

Jet sold lower temp stats, they were required to get full benifit from thier chips, don't know if they make one for us. I was told that 195 was needed for the emissions equipment, a lower temp could throw a cell, anyone else heard this?

Does the NMCP Heavy Duty Engine Cooling option come with a lower temp thermostat? I heard that it does, but have not been able to verify it.
