Welcome to the forum!

Are you saying that to get it to start you have to hold the throttle part way open? And what is blowing off? The intake manifold can't be blowing off, if so you'd have all sorts of problems. Is just the air intake hose coming loose at the throttle body? If so, that's probably the cause. Any air entering the intake system after the Mass Air Flow (MAF) sensor will behave as a vacuum leak. And if the air tube is coming off of the throttle body, that's after the MAF and a large vacuum leak.

I'm assuming your SHO does not have a turbo or super charger installed, so you shouldn't be getting enough pressure to blow the air tube off. That is unless your cam gear has walked, valves aren't closing and the cylinder is pumping air back into your intake. When cranking the engine can you feel air being forced out of the throttle body?
