Default Idle rough at stop sign

Hello -
I have a 1995 with a Vortec supercharger. Just got finished with:
1. New opti (I am an expert at this repair now)
2. New water pump
3. New wires
4. New Plugs
5. New 02 sensors

At a light or stop sign the car does not idle the best - I put in neutral and it smooths out (but not like my 1999 BMW).

When I took to Ellis Groo at Speed Secrets here in Snohomish Wa. He said when he puts a supercharger in a car he normally changes transmission (I quote "thats alot of stuff your running off of the engine") to a more heavy duty type (he told the name, but I can't remember what I had for breakfast let alone a transmission number)

So here is my question - could this be true? The car has never really idled the best - but it is no worse than before I did all the work. Once the car is going it works dandy.

The reason I did all the work was the water pump oil seal died and leaked oil all over opti yada,yada - you guys kno the drill. Anyway any ideas?

By the way if you guys need a hand putting in an opti I am your man -

First Question: Engine otherwise stock ?
Second Question: Injectors ?

Engine is stock (as far as I can tell). You question of injectors is a puzzelment. Yes, it has injectors but are you asking for the size and type (if so how can I supply that information to you?). I have not changed anything since I bought car (2 years ago). The supercharger was installed by the Granitelli Bros in SoCal. So what ever came in kit from vortect was put on car as far as I can tell.

No headers but I have been thinking about that.
Thanks in advance Jim
