I’m stuck right now as I have to get this sorted quick. I’m driving to Denver to take my daughter to school. Much appreciate any help.

URD 7th isn’t mandatory, never was. The supercharger will run fine off stock ECU without fuel mods. It may ping at lower rpm’s under load. It’s easy to avoid these in a manual as you simply kick it down a gear.
To alleviate your concern: I ran my supercharger for over 3 years on stock ECU with only the larger fuel pump. No 7th. No piggy back. No tune. It pinged at specific load/rpm ranges, but I just avoided those areas. So electrically bypassing or removing the URD computer is fine.
For root of problem: I would guess it’s a connection issue. But to help we would need some more info. Like what sort of connection, in general is between the stock harness and the URD? Is it a homemade one with butt connectors? Is it hardwired with soldered wires? Is it one of those fancy million-wire bridge connector things?
I would eliminate the vehicle’s stock components being and issue first by bypassing as you are doing. Then at least you know it’s either a connection issue, or the URD itself is acting funny.
