NNBD

oh and by the way, i forgot to mention that the rattle or probable detonation was @5000 rpm with NO boost...so i think -1 ign retard might be enough but that its something else thats causing it to detonate. Probably base timing indeed. If its way off it will detonate (every car will). As i said..ill check that. If its set right...then i probably won't find it easily and bring it back to stock. I do hope its the base timing thats way off. This way it will probably be fixed.

I still don't know exacly what you mean with the 14 degrees @ +9psi. Call me stupid but i probably have to see it to understand what U mean

To be honest I am ashamed of myself as being a student in enginering (although im more into dynamic and mechanical systems, aerodynamics etc)

oh sorry i didn't read well, you mean for the entire +9psi no more than 14...so also in the 7000 rpm region... ? if so i got to read better..sorry

It does mean that my retard would be a bit more than -2 per psi which is allot i think..
