it might have to do with the VVEL and the ECU. VVEL opens the intake valve wide open when you get on it allow for more air intake. mabye at such a low rpm it forces it to tun too lean flooding the cylinder with air until the ECU corrects and the injectors spray more fuel. mabye thats where the lag and sudden power is coming from and why its corrected when you tune. If you are going at a higher rpm there is more fuel being put into the cylinder and mabye thats why at higher rpm's (i.e. 3,500) there is nothing but power. I know when your MAF sensor is messed up that theres a lag when you get on it. the car runs too lean and there is a huge cut off at a certain rpm (3,000 rpm for me in scion tc). thats how it to me when this happens. My 2 cents and thoughts.
