Great - that's good to know.  As predicted, I have more questions now....

Let's say I wasn't quite honest when I said "basically stock".

Let's say that I have a Vortech supercharger and that I know that
I'm a little lean in the upper rpm range where it's starting to
really put out some boost....  (uh oh - detonation!)

Is there an easy way to use this 9th injector(the cold-start one)
to help keep me out of detonation - mainly as a crutch for
too small factory injectors??  I know I don't want to keep
raising the fuel pressure because the injectors don't last
long under 80+psi right??    So maybe use an rpm activated
switch to trigger this injector at say 3500rpm???  Is this
feasible??

thanks again for any insight!
