Ok so i had just instaled my OTTP stage 2 with a 2.7 and started it up and threw a CEL and the engin light with the arrow pointing down and i put it on the scanner and it threw P0223 and i have no power itss like the supercharger isnt even there. If anyone has any idea wat it could be plz help.

 

how loose is serp. belt??

 

Your in limp mode, check all connections to your throttle body.

 

ive checked everything all vac lins are fine and the iddle is peferct not rough at all its like there a button that turns the supercharger off and its off

 

Its the code for the tps sensor meaning the one at the gas pedal i think im not 100% sure they are known for freying and cauing limp mode issues. Id re check all connection... Since you took the supercharger off id make sure the connectors on the pigtail are good and no issue and clean. Id also check the throttle body for a bent pin.

 

i had t put in a new accl peddle cause i was getting another CEL about 3 weeks ago was running fin till now ive gone threw every conection every line that got the the supercharger i am clueless at this point

 

Sounds like you have a vacuum line hooked up wrong somewhere, I had the same issue, I had two mixed up near the boost solenoid, it wouldn't make more then 5 psi at wot

 

mine wont make over 5pi but all lines are where they should be but i just noticed there is a sencor near the TB bolted to the ead and on te bottem it look like there is a hose that goes to it but the thing is wen i bought it there never was a hose on it
