Default Throttle surge, No boost

Ok, i just installed my turbo and got it runnin today...my charge pipe guy is real busy so i gotta wait to get a proper intercooler and charge pipes. So i used a ghetto *** charge pipe system, and a bov that i had sittin around. So anyway, I went for a drive, and not only was I making no boost, but every once in a while my throttle kinda takes over, i can take my foot right off, it surges up to like 4,5,6k rpm for no reason, if I hit the gas it settles down, im thinkin TPS. But yah, I cant hear the turbo spooling and im gettin no boost. I already tried taking the vac line off of my wg and climbin rpm slowly, still no boost. I know it cant be a turbo related problem because before I hooked up my charge pipes I took the car for a drive with just a filter in my intake manifold and open turbo I guess you could call it, I could hear the turbo spool.

it could be your cable sticking or there`s a vaccum leak, it could be a leak along your vaccume line, also check your BOV and WG coz i`ve seen similar problem caused by a broken /misaligned inner gasket.

yeah....I didnt see any leaks in my ghetto charge piping so I was almost eliminating that from the possibilities...but I did find a leak now, still got the throttle problem........
