The only way that would effect compression is if the injectors fire directly into the cylinder. Very few cars have that sort of fuel injection system. Our cars inject fuel into the intake runners just before the valves. So the valve would stop any air from escaping on the compression stroke. The injectors can however be a source for boost leak.
we need direct injection for our DSM's!!
