Boost issue with GTRS...
 
I recently had my gtrs kit installed. Upon turning the manual boost controller all the way up, I only experience 15 psi. I heard that this can be an issue with the absence of an n75 valve. Would adding an n75 valve correct the problem? I have also noticed some throttle cut between 5k-6k RPM. Any help is much appreciated.

Sounds to me like you MBC isnt installed correctly and the wastegate is controlling boost.

what software are you running?

unitronic, which doesn't have n75 programming iirc

When i initially got the car back it was boosting 10 psi, and I turned it up to 15
