Default tc lags in power problem

so sadly to say my tc motor blew up. nd i put in another motor. i had two check engine codes pop up nd it was the cam position sensor nd a cel code got that fixed so my check engine light is off here is my main issue. I drove it for the first time nd 1st gear was fine nd when i shift it to 2nd gear it lags major power. i even tried to have the gas peddle all the way to the floor nd nothing. its super slow. i got new spark plugs nd coils so that cant be the issue. could it possibly be theres not enough gas going threw the injectors? so right now im pretty freakin clueless.

Have you tried disconnecting the battery for 20 minutes so that the ECU can reset and relearn the fuel trim values again? You went from turbo to N/A so maybe the ECU has the values from fighting with the FIC and needs to be reset....

I was throwing a cam position sensor code and ended up replacing the vvt-i motor. Fixed the problem.
