Stumbling from stop whin cold. Plug gap?
 

Yesterday I started my car (cold) and went to the stop sign at the end of my street. When I pulled away it stumbled.This is the first time I had this happen. I'm a bit comcerned. I'm running platinum plugs gapped at 0.034. Does anyone know the optimimum plug gap and plug type for a 3.0 engine with a Pes Supercharger? Hugo at Pes said It was OK, but I'd like a second opinion.

Most guys runnin blowers when they raise te boost or add on a not stock source of it gap down. I run .028 with my speed tuning chip and it was in direct response to a slight stumbling,goin 2 full boost from a putt, putt roll. Thats with an A4 1.8t with a speed tuning chip. It pulls a lil better 2. My Mr2 supercharged i ran the .028 gap 2 with desirable results.
