A friend has an 02 Z06 w/ a 383 in it. Car Runs great it just surges real bad ay idle. (Like everyones). He has a pretty big cam init 242/247 605/619 w/ a 112 lobe seperation. Another problem is he has an aluminum flywheel. Can some people that has motors simalar to this please chime in or log there tunes for me to look at. He is running open loop and closed loop.
