even if fbo sets the curve for YOUR engine in YOUR car, what if you put it in something else? won't be able to tune it yourself. msd is modular. i have had bad distributors out of the box by msd. so what.... the multi spark helps with cleaner combustion chambers below 3000rpm, but also offers a bigger spark. have you ever been shocked by a orange box? yeah right...... i did the stupid mistake of trying to check spark years ago on a msd system and i basically had a shock run up my arm, across my chest, and out the other arm to ground on the vehicle. my arm hurt for 2 days. is that a better spark??? damn right it is...........
once again, not trying to bash don at fbo. for a stock looking system, he is probably doing the best there is.
