does anybody have a 5th gen prelude with a turbo kit and if so what are you doing with the vtec ? we have a loss of power when vtec hits in the prelude? we have drag gen 3 set up with vafc and avcr

Maybe because VTEC is engaging the same time as the boost comes in. You could try getting a VTEC controller such as the V-AFC and change the engagement point to see if it helps.
