ok here's what going on. first my truck got quiet. She is normally pretty loud. you can hear her a block away. I can no longer black smoke. She struggles in over drive (dead pedal) and does not like going over 60mph. I can't get the rpm's over 1700. The turbo engages but you have to struggle to hear it. She starts on half a crank and shuts off when key is turned off. Oh i bought her with the S&B ram air system in it if that makes any difference.
