The man speaks the truth. You can make some extra power with a VAFC by modifying the Air-Fuel Ratios and vtec engagement. Ver. 2 also has a knock-sensor on it which helps if you ever plan on turbo'ing or advancing the timing. VAFC's go for about $350-$400 new or $250 used.

But you'd be fine to do the whole I/H/E thing first and reset your ECU. OBD-II Honda computers learn really quick and resetting can actually give you a few extra ponies.
