Just wanted to give an update...I waited for the car to warm fully and on the way home from work tonight the boost was back to 14psi with a idle vac of 21 compared to 11 psi with an idle vac of 29....so it is definitely fluctuating regardless of engine temp...

Also, I do have one mod...injen intake.

If I were to log the car what would be my next step?


Thanks for the help.
