(Hypertech) Got it from my local Autozone.
It has not been installed yet.
I plan on giving it a try this spring.
The car has an annoying detonation problem that does not seem to go away.
Once installed and running for awhile, I'll post my results.
Having an Xcal2 might also help me monitor the system as well.
It is not an A/F problem from what the dyno tells me.

no idea on the LS1
i'd think that the knocking problem was due to too much spark advance. i doubt that 20 deg cooler air charge will elliminate detination.

Have you tried using gas from a different station/brand? I've had a tank of bad gas before, car ran like crap and pinged badly.
Just a thought.
Bullitt said:unless the intake has coolant running through it (i can't tell from cutaway shots, but it doesn't look like coolant flows through the intake) you're NOT going to get much cooler intake charge from a lower temp thermostat.
aluminum headed cars want to run at least 180 to get a good burn in the combustion chamber. the only way a 160 thermostat would help is if the map is too lean to begin with and the "warmup" mixture is closer to optimum. as several have noted, your mileage is going to decrease and you're going to build up oil sludge.
you'll do more harm than good by going with a 160.
