I've read many debates on the topic on different forums namely turbobuick & syty so figured It would be interesting to get the thoughts of those here.. I'm a no lower than 180 guy but even at that I'm Leary of messing with GM's engineering decisions

Which do you prefer, why?

Unless you are actually returning the engine (changing parameters in the ECU, changing supercharger pulley, switching to copper plugs) I prefer the stock 192F thermostat BUT I would also install a higher pressure radiator cap (say 16lb) because as the caps age they weaken and it does not take but so many years for the 15lb cap to start contributing to headaches.

I agree with you.  The PCM doesn't think the engine is "up to temp" until it reaches nearly 160, so that's a bad idea unless as Albert said, you're making major modifications...  Also, I believe that stock pressure cap is 16 PSI already - or at least that's what came up the last time a bought a new Lev-R-Vent.
