Ken I'm just about ready to get mine back from vengeance. I hope they did do some things to help you with heat as that is really one of the main issues with forward facing headers. I've upgraded my radiator and went with a lower thermostat. I went away from the shiny ceramic coated headers to wrap that helps with heat. My saga seems to never end. I just new tune awakens this beast to what I was expecting. If not someone will get a car real cheap and I'll be riding in a stingray..
