Any problems? Missfires? Its better, smoother? Worse?
Smoother idle at 850rpm hot with no small "misses" at idle. No misfires in the midrange when the high torque boost spike hits at 27psi - previously with the old dizzy it would miss some days and not others - coilpack cured this. More fuel economy aswell (only a couple of mpg), engine sounded generally healthier aswell (placebo effect maybe?) and the car drove better aswell.
