dude my car has been doing the same thing and a lot of my buddies have to...i used a different gas station and put a bottle of injector cleaner in the tank and it has stopped breaking up now...

May need to be tuned, especially if you didn't get one after not having the supercharger anymore and still running 42lb injectors.

definately you probably need a tune cause your basically running a stock engine with way oversized injectors, or buy smaller injectors.
What is happening is when you go to wide open throttle the computer is telling the injectors (thinking they are stock injectors) to dump all the fuel they can, with the bigger ones its dumping more than you need.
