Two things to check:
The jerking can be from the ECU cutting the fuel injection if the boost is too high. If the boost on the indicator goes 30-40% into the red, thats where this can occur. If so, the wastegate or a hose to it or the BPC valve might be bad. Normal boost is just to the start of the red.
Pull the plugs and inpect them. If they are carbon fouled, the spark will track across the carbon at higher pressures. if so, get the right plugs. NGK BPCR6ES11's and gap to .035"
If the above does not help, post that.
