    if file is done by a decent tuner they can remove fuel to reduce some cylinder pressure. not as effective as reducing compression but it can help. consequently it will loose a bot of power.

    C13 runs lower compression @ 17:1. Proper tuning and they do fine. C15 is different story.

    all 13's 17:1? I'm not overly familiar with C13 ACERT

    I know with 15's 475-550hp is 18:1 and 600-625 are 17:1

    Yep, all KCB are 17:1. Same iron set for all ratings. Never messed with LEE (spark plugs engines), so can't say for sure on them.
