Looks like the Predator CAI/93 octane tune + AirHammer yielded some big gains for me, from 351 to 393 RWHP!
This must be near the top of the range of what can be expected. I suspect she was undertuned from the factory and these mods really woke things up.
Very nice gain and smooth curves, congrats. You are one of the few who took the time to get a baseline. It feels so much better with the Predator, huh?

Thanks!
I also got the 180° t-stat installed but we did not change the fan settings via the Predator. Nevertheless, it is running much cooler now, about 190° on the highway. I read somewhere that a 180 tstat would do nothing by itself unless the fans were reset, but mine sure did.

Congrats on the gains, the Predator really makes a big difference for these cars doesn't it?
I read that all the time about the tstat too, but like you I noticed an immediate drop in temps across the board, and adjusting the fan-on temps made it even better.

When you're running fast enough the air flow through the radiator will keep the temps down with the 180 Tstat. However in city traffic you will notice the temps rise to "normal" if you don't have fan settings to accomodate the lower Tstat. My cars run right at 183-185 on the highway A/C on or off. But in town you can hear the high speed fan kick on starting at 195 F and then off again by 186 F or so.

^^^What he said, except when I run the AC on outside air to smoke, and the outside temp is high, I go up to about 190 on the highway.
Right on. I'll have the fan settings adjusted eventually.
I understand there are multiple settings, not simply 185/195° low/high.
How do you have yours set?
