I have used a pump from a one man bleeder set that has a gauge and hooked it up to a vacuum line and pumped it to about 10 and seen if it bleeded off.

I worked on a car that did the exact same thing and it was the VATS (vehicle anti theft system). I turned the VATS off in HPtuners and it ran fine. Nothing you did should have messed with the VATS but it may be worth looking into.
