I did some looking and searching but i dont think im am creeping.

I had the car set at 15psi and it would hit and stay solid. Now that i have all the things i need i turned it up to 20psi. Now it will hit 20psi them fall to 15psi and stay. Some times it only falls to 17psi..?
 
This definately sounds like a boost leak. Boost leak test it and get back to us with the results.
 
ya look into your bov -- 15psi to 20 is a big difference and if you 1g bov isnt crushed ( assuming your running a 1g bov ) then maybe she s leaking
 
Yes, I am running the stock 1g bov un crushed. I put on a knock off greddy and adjusted it stiff but it still bled off to 15psi. So I will just have to do a boost leak test.
