We swapped a d16z6 into my friends hatch. Everything went great. Runs fine, got all the codes sorted out, VTEC is engaging. Only problem is that he's not able to hit the rev limit of his p28 which should be 7600 I believe. It falls short (according to the tach) at about 6800 or so. We first suspected the tach, but the tach seems to be showing the right vtec crossover point, so it seems to be accurate.
Any ideas?
