i just put in a 180 degree t-stat today and later on i was checking out www.v6fbody.com. i saw something on there that said if you put a different temp stat in, you have to change the prom. does that apply to our cars or is it 4th gens?

 

I would also like to know.

 

well, the prom is set up to run BEST at the default temperature.

So more than likely, all you are doing is HURTING performance by using a lower stat temp. You probably dont HAVE to get an upgraded chip, but you would notice a better performance increase with one...

 

has anyone out there who did this have any concerns or anything w/ this? the next thing im getting is a new switch out of summit. this freakin car is running constantly over 220 now that michigan finally got summer, lol. i dont have a cooling system problem either, its all new, i mean ALL of it, lol.

 

I run a 180* but I also have a custom 4-core radiator and a different prom with altered fan run temps.

 

anyone out there w/ a 180 t-stat and a stock prom? im not planning on another one for a while yet.

 

Yep, sure do.

Just don't go down to a 160-165 T-stat.

 

I just put a 180 degree thermostat in my car, drilled 4 holes around the outside of the stat too and the only difference I've noticed is my car isn't always running at 220 degrees, it still takes off as fast as it did before, and I don't seem to be getting any worse gas milage so I dunno. I could also be a retard.
