Extremely Rough Idle

Hi guys - I recently purchased that 05 Elise on eBay with the VF Stage 2 supercharger (the one with 8k Miles that a few of us talked about).

It is tuned, has upgraded injectors, I just installed an ACT Clutch, Fidanza flywheel, replaced all fluids, etc. in preparation for tracking regularly.

Long story short after driving it this morning I came to a stop and the idle was insanely rough. No CEL as of now, but I'm thinking it's one of the following things:

1. Loose ground on the left of the engine

2. Disconnected intercooler piping somewhere

3. Vacuum Switch Valve is loose

4. Fuel Pump priming or check valve (I hear it prime but it's quite after starting)

The car will sputter until about 3k RMP and then come to life. I have a track event saturday so any insight would be greatly appreciated!
