boost controller?

[my95tsi]

Ok i just put in my dave brode uicp and my 1g bov. My car hits 15psi perfectly then creeps to as much as 21psi in higher gears. So i put my bcs back in and the car hits 15 psi sometimes. Other times it will hit 14psi only and as much as 16 psi. But it fluctuates too much and it also drops sometimes back to the stock 12psi in the end of gears. My question is will a joe p boost controller help the inconsistency? I just want it at 15psi maybe 16 and i don't want it to go down to 12psi. I don't have a exhaust yet but a catback and test pipe are coming in just over a month. I'm going to wait awhile on the downpipe.

Thanks!

SEARCH.... please. The t25 sucks ass. No matter what its going to drop boost at higher rpm. The joe p will help you hit the 15psi stay there for a bit. But it will drop to around 12psi no matter what on the t25

Sounds like you wastgate is to small. Port it or get a better turbo.
