The lag you are feeling is actually the traction control cutting in. If you have JB4 do some logs from a dead stop and traction control on. You will see that the pedal is being pressed, but the throttle and fuel are being cut. It's basically how the computer stops you from spinning the tires off a dead stop. Our cars have a lot of torque because of the turbo. Try this, hold down the DTC button on the dash until the triangle with the arrow going in a circle shows up on the dash. Then jam the gas from a dead stop. No more lag, but you will spin the tires like crazy. Be careful.
