I was driving on the highway the other day and when I hit the gas, a lot of white-blue smoke came out the exhaust. The acceleration after that was very poor. Also on startups white smoke comes out of tail pipe. Scan for codes and got p0171, p0174 (twice) and p0022. Please help, I’m completely dumbfounded.

If the pro charger is mounted near the driver side of the engine, I would check the wiring at the cam solenoids. I have installed several superchargers at my dealership and I know that the wiring can be tedious, but I hope I get you on the right track anyways. As far as the lean codes, make sure all of the intake plumbing is secure and also would not be a bad idea to clean the mass airflow sensor. Also, check for excess oil in the intake, it is common with supercharged vehicles. A catch can is a good thing to have for that. These things are preliminary things to check, so let us know what you find and we can go from there.
