Default my mustang is jerking while driving

I have a 2002 mustang GT. 5 speed and i just installed a vortech V-2 Supercharger on it. and ever since then the car has been jerking while im driving. It doesnt jerk at all when im accelarating, its only when i let of the gas not enough to slow down but just enough to maintain a constant speed. Does anyone know what is causing this and why. any information will be helpfull. Thanks

Sounds like your by pass valve is either not working or is pointing towards the MAF.
