xnamerxx: Explain to me how this matters, hes not running a stock cam iirc and not only that he doesn't have a stock intake and why dont his torque numbers drop sharply like they would if he fell out of the stock cams torque band. Not only that doesnt Garm use stock cams with vvti turned off.
You cannot compare Garms build to xB build to Art's build. They are all different. The only thing they have in common is the the are turbocharged.
I wont say im a expert at tuning but what im seeing on his dyno sheet is very obvious to whats going on. Im not saying maxing the turbo out is bad just saying he did that and his dyno proves it.
What is obviously going on?
As for running lean its not detonation you need to worry about its going to be scuffing pistons and cracking rings and ringlands and pre-ignition.
How do pistons get "scuffed"
BTW detonation & pre ignition is the same thing....
