PM Rob, Crash, There are not marking on the injectors, they were but in by the previous owner, they are not stock that is the only thing i know for sure about them...Id like to test the duty cycle for sure before go drop a grand on some id1050's..at which point i would need a dual fuel pump im guessing.

You actually pulled an injector to see if it was marked as that would seem like a lot of work.

I want to pull one but the whole fuel rail coming off and all kinds of goodies is turning me away from that course of action

You cant pull the fuel rail without grinding a boss on the super charger lid... unless the lid came off, if there is no grinded portion on the front drivers of the lid side assume you have stock injectors

How much boost?) I'd gap it out to at least 0.033-0.035 if it were me. I'm at 0.039" with 7ix's at 12.5-13psi, and was at 0.039" at 15 psi before the cam, too, FWIW.

I just changed my plugs. I went with TR7, but gapped .038.
Gapped at .027 is to tight.
