Ok well after correctly hooking up my boost gauge i realize im having some creep problems which I don't know if its normal with the 14b. I have my mbc all the way down so I should just be going off waste gate pressure which is 10psi right? (its only at low boost because I know I have a boost leak, and it seems to help) But when im at WOT my boost jumps to about 12.5 to 13 psi and steadily falls to 10 and sometimes lower. Is this normal for the 14b on a 2g? All my mods are in my profile except for the greddy bov because im still waiting on a adapter that actually works. ( the one I ordered on ebay didn't work) Any help or opinions would be great.
 
I was working on a 2g and I put a mbc on it thinking it would run stock boost with it all the way down....Well I dont know if it was a shitty mbc or what but it would spike like crazy and stay around 17psi....so I decided to take it off and it stopped doing it. Try removing the mbc and run it and see if that changes anything!! It might not but it's a start!!
 
you should not run your car hard with a boost leak.wait until the leak is fixed and see how bad the problem is. also some mbc will still be higher than the wastegate.
 
Before I had my boost controller in my 2g I was in same range.. So I would say its pretty normal be around 13psi and drop back down to 10 to 11psi just before redline.. But this was also with a t25 with just and intake at the time..
