Engine stumbles from stop

[run96k3500]

I been having an issue where once my truck is warmed up, the engine will stumble when I begin a lite acceleration from a complete stop. I have brand new NGK plug, new wires, new MSD StreetFire Distributor with cap and rotor. I can’t seem to figure this out.

This is on a 1996 k3500 with a whipple on a 7.4L

So far I have tried disconnecting the egr connector and plugged the line coming off the evap canister.
