Freerevving when started...

Well i just installed new injectors and turbo. Put it all back together, replaced all vacuum lines, gaskets etc. Load my base map and it was running fine. Let it warm up and tapped the gas a little and it just started freerevving. I shut it down, checked all connections, linkage, etc. I started it back up and it just shoots straight to 4grand so i quickly shut it off. Double checked everything and reloaded my base map. Same thing just freerevs. Ive checked my Tps, its in spec. I tryed unplugging my BAC and it would let it idle but jumpy. So i took off my bac and tried cleaning it as recommended by a member on here. The valve that opens in there only opens like a eighth of a inch on mine, dont know if thats normal or not. Put it back on and same ****, just trys to rev up. I once again tried to disconnect it and NOW it wont let the car idle at all, connected or disconnected it still just freerevs when started. Im so fed up with this car, its just one thing after another. I was supposed to be heading to St. Louis right now to get tuned. This sucks so any help would be much appreciated. I mean i cant even get the damn thing warmed up now because it just revvvvssss, let alone drive it.
