I know I already asked about this but I just read a thread on another site that 160 degrees would throw a code and lower fuel mileage. Is that true?

Sounds right...a cooler running engine will typically run richer, thus using more fuel.

Yeah... anyone else have an opinion?

The more I read, the more negatives pop up on the 160...

I'd stay away from a 160. There's not a lot of engines out there that actually need one an most people that do usually don't run a t-stat at all. I'd go with the 180 and call it done

So 180 won't throw any codes? And it won't mess with my mileage at all right?

Do you understand why I am though?

Part of what Adam said is correct. In a boosted engine you want to run the af on the rich side. Better to have a bit more fuel than not enough and shit start's "pinging" which is detonation. What I was explaining about the CC temp's really dont have much to do with NA engine's. Just remember, the cooler an engine run's, the longer it last and better it run's. The CEL can be deleted in 9 secs and i'll take a 2mpg drop over keeping an engine running longer anyday.

Yes it will... Stock is 190.

See some stuff i read said that running cooler will make the engine not last as long, said that it would dump to much fuel trying to make up for the lost temp and in turn worst mileage

And yes i do understand that, all i have is a cai and exhaust, so 160 would run to rich for me then right?
