if i were to buy a vafc2 and set it at say... 4800, would it take away from my top end?

is 4800 just a random number? Leave it alone unless you are going to tune it.

Just so you know.....vtec doesn't "run out" or anything if you engage earlier. lol

So no, it wouldn't hurt your "top end" power but it would most likely cause a big dip in your midrange powerband.

Like Blake said. Tune it.

4900-5000 has been MY sweet spot.....a 100 rpm change in the wrong direction has caused HUGE losses into the double digits.....
Dyno or don't bother....

If he's running a stock set up, isnt 4800 on a vfac just going to cause a power loss?

98vtec

maybe, maybe not.

no one will know without a dyno...unless his butt dyno is super accurate.

No loss in top end...I also have mine set at a 4900rpm activation point, but as the guys mentioned earlier, you might get a some hesitation if not properly tuned. Try to get some tuning done whenever you decide to give it a try, preferably on a dyno so that you can monitor the changes.
