Gt2871r-15 .64 boost creep

Need some help here it doesnt make sense to me.
But I went in for a tune today on the new setup and its hitting 18psi by 5500 rpm and creeping up from there.

The turbo is brand new with a 12-14psi internal wastegate, shouldnt the wastegate be opening within that range and keeping the boost Down? Currently bypassing the boost solenoid so theres no interference between boost and wastegate.

Shop is suggesting I need an 8-10 psi wastegate but I cant understand why that would matter, feel like if this was a common problem with this turbo there would be more posted on it but I cant find it or Im looking in the wrong place

Setup below
Kouki s14 SR
Tomei manifold
