Lean at Idle

I have a 92 Camaro with a ZZ4 bottom end, edelbrock aluminum heads, a comp cam, edelbrock TPI manifold and runners, and some other goodies including a Vortech supercharger and some 32 lbs/hr. injectors. The engine runs pretty good at the top end but seems to have a small miss which is more apparent at idle. I recently added an Innovate motorsports AFR gauge and sensor and no matter what I do to the VE, pulse width offset, or flow rate I cannot get it to go rich at idle or with no boost. I was wondering if anybody has ever had any problems with injectors causing this or if there is something else i should be tuning(making adjustments too)?
