ok, i got a 95 vx with b18c1 swap. i installed my vafc recently but something is not right. if i change the vtec point, say to 4800rpm, you can hear the vtec kick in at 4800, but you cant feel it til 5800 (stock vtec point on p72).. anyone know why it is doing this? i check my vafc wiring several times and everything seems to be right. any hlep?

 

only way to truly tune with a VAFC is on a dyno.
