baby type r

I recently put an ls/vtec in my eg hatch. It is fully built, forged crank, 12:5:1 pistons, forged rods, skunk2 pro 2 cams and gears, Skunk2 valve springs and retainers and more. the car cranks and idles but has a surge to it. I have had people look at it and they don't know what is wrong with it. When I try to take off at a slow speed it will all of a sudden surge and the rpm's go up to like 4,000 with just a very little gas being applied. Any help on this situation would be greatly appreciated. I looked online for similar problems but found nothing.
