Default overboosting..

I just changed intercoolers, small fmic to larger fmic. Anyways i am now spiking and holding well past my boost guages 25. Is my list of things to check a good start or anything I am missing. N75 hoses, wastegate (possible stuck) L-hose...vacumme hoses possibly pinched. The car has a gtrs with mika software and before i never saw over 19 although i do know my old intercooler had a large leak, 25+ seems obsurd. thanks for any input

Default You can never have enough boost...

Are you sure your gauge is accurate? Spikes to 25+ are not so bad, my k04 is there frequently. Hold though on a GTRS I am not familiar with what your software calls for.
Do you have a log of requested v's actual boost?

Default Thats what i have to do this week if i get time to do some logs, its odd since before it was.

spiking 19, now 25+ has me worried. logs will help though. true tho, more boost = more fun (generally)
