I could be wrong on this one but sounds to me like your running to small of an injector. Your soft code is probably a lean code, since your under full throttle the computer is unable to add the extra fuel that your engine now needs do to the upgrades. ID recommend going with atleast a 24lb injectors and matching MAF sensor. You could try upping the fuel pressure to say about 45. UP it in small amounts and see if your check engine light stops coming on.If you havent upgraded your fuel pump, u might look into that. Fuel pumps are inexpensive insurance. Definetly help with TOP END fuel starvation problems. Good luck
