I've had similar problems with my S/C setup also. 1st time found the vaccum/boost sensor had popped out, easy find and fix. 2nd time it ended up being a failing TPS sensor. There is a re-calibrate procedure, which worked for a while but I ended up replacing it via Autozone. Simple swap-out was worth it, the shaft had cracked in the original one. When the ECU can't read the throttle position properly it lets the vaccum signal tell it what it needs to do about the fuel injection which is inaccurate and laggy. Good luck!
