    ECU, Distributor, etc?

    you really need to give more information. what car? wha engine? what ecu?

    but to throw out a random possibility, maybe you have low oil pressure and you dont build enough pressure to activate vtec til 6k. maybe your tachometer is off.

    i have the answer. if its a gsr engine, then you are hearing the IAB's. when i had my IAB's still on my gsr, they were louder and more noticable then vtec.

    if not then like B said, your shits fucked up

    Exactly. The IABs open at just over 5800 rpm. That's what you're hearing.

    The IABs basically allow your motor to use a smaller intake plenum at lower RPMs for better low RPM power, and a larger plenum at > 5800 rpm for better flow at higher RPM's.

    my vtec engages at 5300, any higher or lower and it is pure shit. get another ecu and see what happens. 4500 is stock GSR i believe, chipping is a poor man's tuning, get a e-mange, hondata, aem,. etc.....

    B16 VTEC is 5800 GSR is 4400. if you have a B16 then its normal. stock tachs suck ass its really at 5800 when it hits though it might read 6K. ive seen a stock tach read 9K at 8400 RPMS
