Rpms wont go 3000

I'd have to agree with Smithbrother and go for the valve body control.........sometimes soenthing simple goes unchecked...make sure your tach is okay.

change the dist.coil pack and electrnic spark control module autozone 135.99 control module 31.99 for coil pack each

SOURCE: engine has no power under 3000 rpm

have a look at the EGR valve if its stuck open you loos all the turbo boost till the EGR valve closes
it could also be the turbo gate valve (wast gate) sticking open so the turbo cant cut in till its screeming then the gate shuts and the old girl picks up her skirts and go's,,, you may get away with just blanking off the EGR valves to try them out but the turbo is a different mater,,,
