if your wastegate is stuck completely open you will build boost slow as a motherfucker, and won't hold steady boost anywhere, you'll just build it real slow and it'll keep building until you shift.

I'm guessing you have your BC hooked up wrong. Mine does the same thing (but at 10psi) when my neat friends play a joke on me and put it in backwards.

my boost controller is right i have everything set up like it was b4 the turbo change. even if it was wrong with a open wastegate it would spool past 7psi i would think

the wastegate actuator is either bent or the diaphram is busted, or the wastegate flapper has been ported so much that the flapper doesnt cover the hole completely, or the flapper is stuck open. try getting another actuator first. i posted a few times on here WTB 14b/TD05H wastegate actuator and someone had one every time for about 20 bucks. shouldnt be hard to get. good luck.
