Exactly, the power surge is due to increase of airflow in the cylinders when all the intake ports open, but it is also because the ECU changes the timing. The IMRC isn`t removed, it is plugged in (the cable is also hooked up), I just pulled the linkage fully open. My cel bulb is certainly removed because I`ve made the mistake of buying the car from a boy racer and developed quite a few problems right after I bought it, a blowing head gasket would be the most important (only half compression on cylinder #3), and I`m sure that because of this i`d had at least an O2 sensor check if i`d pull the codes, but still no cel. Before I fix the IMRC got the replace one head gasket, and then that problematic transistor inside the IMRC (which was dying anyway, would only work when the engine was cold, but last time I checked it was dead even with a cold engine). With all this crap, I`m not even expecting the engine to develop full power, and when I drive it, untill got the head gasket replaced (it just blows, no oil and coolant mix, no smoke) i just keep it under 3000 rpms anyway.
