Yes Jeremy i am mad , thats why im in this business lol

There is no way you can limit an engines temp range for tuning, you tune for performance and where ever the engines temp is at peak tune thats where it like to be.. pretty simple.. If you were to tune to temp , lets say you get it to 120 deg c then change the pipe, 9 times out of 10 the temp will change, then if you change the fuel , it will change again, if you change the body , tires , surface , air filter .. all these things will change the engine temps. So that why i dont bother with it, I tune for performance only adn the logevity of my engines and that of my racing team is better for it .. Im just stating real time experience..

Anyway its a scarry thought to run engines that hot but believe me they dont mind it at all .. A well built engine should lean choke on fuel intake before it causes a malfunctoin.. it a malfunction occours running at say 140 deg c theres a good chance that the engine materials couldnt handle it.
