Default Car acting weird, advice?

Well i just got my smaller pulley in my p1 and it hit 16 psi and 6200.. i have a walbro 255 and 60lb siemen injectors. Everything is tuned. Now i did a run and its awesome. Plugs are gapped to .30, everythings fine. I decided to give my friend a ride and at 5200, it starts to shake. Kind of like a fuel cut. Now that is my first problem. 2nd is, cruising at 1500 rpms, the car shakes. When i give it gas to go, its fine. Only when barely touching the gas to cruise, it shakes. It never did that before. I dont know whats up. Lose plug or wire? I jsut had my mechanic install Autolites 103, much colder plugs. Im sure he didnt mess up on the plugs or wires so i dont know what it can be. Any input?

Might have better luck in the Forced Induction or Fuel area?

Exclamation

This has nothing to do with this setcion (General LSX Automobile Discussion).
Try the LT1 section and maybe Forced Induction section. Also max is one bump per day.
