The ceramic coating will help with the temps and the new turbo plus cam are supposed to reduce exhaust gas temps. Steel pistons would the the balance way out, plus I'm not getting that crazy.
Took it for a test run today! What a difference! It doesn't belch black smoke when I stomp on it and the egt's are about 300 degrees cooler too when pulling hill. Can't wait to see how it does towing my camper.
