There is no way it can be done without the aid of modern electronics. How can you combat something that you can't see or hear? Only electronics is going to be able to help out because it detects and corrects before you even know whats going on. You will either be melting pistons without it or having the timing so low that you can't possibly hurt anything, but leave 30-40 HP on the table. In that case, the biggest waste of money of all will be the turbo itself if you can't use it to its fullest potential.
Well then I'll try and factor it into my budget.
I've read about about people using special acoustic devices to hear or read knocks. Also I didn't know if there was some indication tuners could use like EGTs or HP relative to timing increase or something.
