just put in a vtec light to due to the fact that vtec in not noticable on sohc and i wasnt sure if it was working. well vtec is working but kicking at 4500. it is chipped but vtec should be at 5200 w/ a 7200 rev limit and a 4000 lauch. well vtec hits at 4500 rev limit is 6500 and lauch is 4000. could my tach be that far off. or is there a chance that i got the wrong chip or a bad burn????
