160 degree stat/tune question

Hello all. I had a 160 stat installed along with a PCM tune to match. After recently having to remove the intake manifold, I found yellow condensation snot all over the bottom of it. I have since put a 180 stat in, thinking that might help. Do you think it causes any problems have a 180 stat but a tune for the 160? Should I put a 160 back in? I dont have the funds/time to re-flash the PCM. Input would be great appreciated. Thanks!

Depending upon what was flashed, you shouldn't have any issues.

It was a tune by Pcmforless. My understanding is that the cooling fan temps where lowered and the timing advanced a tiny bit.

I said "flashed" but meant inputted into the pcm. Usually, just some of the "limits" change to account for the lower t-stat.

This really has nothing to do with the question (I don't know the answer), but an interesting read about "colder thermostats" nonetheless...

Benefits of using a "colder" T-Stat? Virtually none - but there usually are 'bad" side effects of it - at least according to this article:

http://www.tuneruniversity.com/blog/...the-advantage/

Bottom line - the people who designed the engine are perfectly capable of determining the best t-stat temperature to use - no need to mess with it for a "street car" - or even for a race car for the most part. :-)
