Naaaa! You will need the boost-sensitive type. As always, consider the
extreme version of your scenario. You have, say, 40psi fuel pressure at
idle. Your boost goes to 10psi - no problem.
20psi...hmm, seems ok.
41psi...the boost pressure is now trying to force the fuel BACK through the

Never mind what on-time you give the injector, the injector has to spray,
not dribble. Whatever your fuel pressure is off boost, it should stay that
much ABOVE boost pressure all the time to maintain a good spray pattern.
