RFd15bhatch

I have a 95 civic hb with a jdm d15b swap, it's been a nightmare getting this thing going. I finally got it running and the car throws a v-tec pressure switch code, and completly falls on it's face in third. My question is could it be timing why it won't get up and go in third. i know what the v-tec pressure switch problem is thats a loose wire, so i know thats not it, even though i am sure v-tec would help a little more. i am thinking timing is the culprit of my lost power in third, and i just wanted so advice from jdm d15b owners.
