Cars auto revving! help!

I just put in a single turbo and when i get it to crank it just starts revving up on its own and i have to kill it cause im scared of it hitting redline. I have no clue whats wrong...

everytime i try to crank it after, its flooded and i have to take out the spark plugs and clean out the fuel and put ATF in to get it to fire back up then the revs just shoot way up. Ive seen it go up to 5,000 rpm in hopes that it will stop revving after 3 - 4 k and it seems liek it doesnt intend on stopping.

I have my maps loaded on my power fc for 4X 850 cc injectors and since the 850s were flooding the engine way worse i put the stock 550s back in just to see if it will not flood with the 550s. could that be an issue?

ive taken the uim off about 3 times rechecking all the connections and all the vaccum lines are in and so are the 4 connectors i still use on the uim. The throttle cable seems fine it only opens when i push down on the pedal...

Back when I took my throttle body off and put it back in I had the same problem. Turned out to be the black covering on the cruise control cable. When I put everything back on, somehow the black cover over the cruise control cable that was crimped backed out and kept tension on the cruise control line, making the motor rev when I started it. Simply take the black cover off the cruise control unit in the corner of the firewall and drive side fender. You'll see that there is a black cover over the cruise control line that is crimped. Make sure it didnt come out, if so, simply re crimp the black line back in and see if it works.

There must be something mechanical that is allowing more air into the engine (throttle stuck open, or huge vacuum leak). Just dumping more fuel alone will not make it rev up.
