if you want HRC's tech support, they are open just about every mon-fri from 1-5 central standard time. 630-801-9065. I am sure he would be able to give you an answer to why "detonation is bad" IF the turbo kit is installed properly, and your engine is in good working order, you should not have "detonation". I have seen wiht my own eyes a motor blow because it just couldn't take it anymore. running the right air/fuel ratio. HRC has put several months into testing their products, and they KNOW what works and what doesn't.

Bring it on............
