my friend and i installed his stage ones the other day. the car runs great with em vtec is so so oh my god . but any way when vtec engages at 4400 or what ever it is on a gsrit lags until 6k. he has the skunk 2 intake manifold as well. what ecu woulsd work so his car isnt running in safety mode with the cel cause of the manifold or does any body know of a way to fix it. cause we need to set vtec at 6k and his vtec controller doesnt work with the cel. thanks
