i get the detonation rattle during acceleration, before it gets to full boost, its not loud as proper det, can only hear it when driving next to a wall or fence. im sure i have heard it a few times, but wasnt sure, i havnt change anything timming wise on the engine in 5 years, but i havnt changed the plugs in bout 3 years so as im running about 10-11 psi boost, what is the best setup for the timming at idle to make sure i keep the acceleration but lose this worry about det.

cheers guys.
