My 99 civic SI is Jackson supercharged, I/H/E, AEM fuel pressure regulator, Hondata, 450 injectors, 12lbs boost. I'm used to naturally aspirated and so I wander on stock internals what should I do next to gain power? I was thinking MSD ignition, cams,timing gears, and accessory pulleys maybe. Would that improve much with a proper tune? I want to do every possible thing I can before maybe tearing it down to do ls/vtec later. What do you guys think?
