Wondering if anyone did a before and after after this install time slip or dyno wise. Doesn't seem to me that claims of increased hp ratings are making total sense as isn't the alternator having to work harder to run the extra electrics? That has to use up some of the gains no? I've heard numbers from 15-25 hp increase but this seems outlandish to me. Sort of when the "cool can" craze hit the 60's and 70's. Never any proof that it actually helped times as opposed to other factors such as better leaves or track conditions.
