Do not touch the gas when starting.

You should slightly looses the screws on the air induction plumbing so that 
if there is a backfire/detonation again, it will pop off only the black 
plastic tube (probably at the AFM connection) and not the plenum, which is 
not only a bigger issue to deal with but can also wreck your hood.  It is a 
wise idea and the conventional wisdom to keep the air induction attachments 
slightly loose on a 6 for just this reason.

Best luck!
