Jayne,
You need to set the timing to 16 degrees before top dead center with a timing light. You will not see high boost levels with the 89 octane gas that you have in the tank. Fill the tank with 93 or 94 octane gas. The "rattling type noise from the engine" that you are hearing is caused by low octane gas and possibly by incorrect timing. It is "knock" or "ping" and it is what causes piston damage.
Have you checked your base boost as per my previous message?
Jon
