Stock temp, hi-flow thermostat should do nicely.

180 is fine. Just will run slightly rich.

If you have to run a lower temp thermostat to keep it cool, you've got other issues to deal with. A hi-flow stock temp will outperform a lower temp anyday. It's about flow, not about temp.

I wouldnt run a 160. Its going to throw fits with your computer. its just going to dump extra wasted fuel. lowest i would go would be a 180 stat.

No dip it doesnt, the computer is still reading from the ACT and TPS to decide on fuel requirements so running it cooler doesnt make it faster. Normal operating temperature is around 210 for these cars.
