Around a month ago, my car only boosted to 7 psi instated of the normal 15. It doesn't throw a cel. It has an intake, upper cp, bypass valve, catless dp, catback, and stock tune. After a day it fixed itself. It happened again about 2 weeks ago and fixed itself again. Over the last 3 days it's happened at least once every day but always eventually goes back to 15 psi. It alwayd goes down to exactly 7 psi max when this happens and has been happening more recently. Any suggestions as to what the problem could be?

Do you have any way to log the car? What are your fuel trims?

You have a lot of stuff done for a stock tune. Check your for boost leaks.

Also try putting the stock intake back on and see if it still does it.

You should really get a tune for all of those mods.
