I would say re-adjust your rpm to 6200 and remove it, this is not the way to get power, putting vtec low it doesn't improve performance, too low you loose as well, too high you loose midrange, Honda set it there because at 6200 is the most beneficial position to be with OEM parts....my ek9 came with a vtec controller when i imported it, but apparently their not worth the hassle and can screw up your engine? if its not worth it should i have it removed? or could i just set it to 6200rpm and leave it there?
