Alright, so a few weeks ago, i tried testing for a boost leak, however it didnt end up working out because i was in too loud of a place. So i gave up, put everything back together and went on my way. Well as soon as i turned on the car, the check engine light was on. I checked the code and it was: P1854 which i found out was TIP BARO OUT OF RANGE. However, the engine light went off like a day later. Also, i have been noticing the boost gauge being really jerky sometimes. I brought it into the dealer about that and they are ordering me a new one which should be in soon. Anyways... i used to boost at exactly 14.5 PSI everytime in 2nd and 3rd, but now i usually hit 12-13 and never above 13. I have tightened everything, etc. but i dont know what it could possibly be. I even disconnected battery to reset PCM. Can anyone help?
