RB25DET S13 not holding boost!

Postby dillon.xvi » Sun Mar 08, 2020 2:59 pm

As title says, my RB isnt holding boost. Boost leak test on intercooler piping checked out and didnt find any leaks.
Im running 14psi and i just don't really know where to start as far as tracking it down. On heavy acceleration, it sounds as if i had a screamer pipe and i don't know if thats connected or not.

I'm currently running:
stock turbo
mambatech internal WG
HKS SSQV blow off valve
ISR down pipe
3" exhaust straight pipe
Haltech platinum pro
generic manual boost controller

The rest of the motor is stock with a front facing intake manifold and a GKTECH fan.
