We used to think that changing to a lower-temp thermostat was a good way to boost performance in a subtle way. With the computer controlling the way the engine operates based on the inputs that it gets from the various sensors, that isn't always the case. I guess that's part of the reason for getting a Programmer, huh? Changing parameters is just another part of the "cure".

Wish I had a programmer for my '96 4.3......yeah, from what I read it's the same one that works for 5.0 and 5.7's.
