I recently bought a 87 GN and I know everything about now,..except the injectors...
They say TOMCO on them with a green lable...
Does anyone know what psi these are? what should my Fuel Pressure be at the rail w/ 17 psi boost?
on a stock chip???92-93octane?
Most likely they are the Tomco "Green stripes" ... basically stock replacement disc style injectors. They are rated at 30# (stock is 28#).
See the Photo Guides:

for a picture of similar style injectors (very rarely do they have the big green label)
