If you have G40 at the cam sprocket then it doesn't need to be separately aligned... G4 is indeed the crank ref sensor - the G40 & G4 pulses should arrive at the same time every other crank rotation... if they are far out of whack you don't even get an engine start so you should be fine although there is great confidence in actually seeing it.
My gut feel is an air leak on this one - you need the bungs and a methodical approach to check everything.
Have you checked for a torn WG diaphragm ?
Might there by a hole in the intercooler that has been overlooked ?
Check you have good solid 5V at the throttle pot and the altitude sensor as well - should be a red wire from memory on each of those when key is ON.
