Title: 1.8t AUM Overboost
Post by: Jordan_gti on 05 October 2017, 17:18

Hi again, im back with boost issues :)

I have a mk4 golf GTI (AUM Engine) 1.8 Turbo. My mods; Forge 008 Recirculation valve, COne filter, 3" full turbo back decat exhaust. It was originally not boosting at all, after a long investigation, I discovered the actuator was stiff and I freed it up & adjusted it and it now boosts to 8psi as it should. However when I get to about 6k revs it jumps up to around 10 PSI. what could cause this?

Side note, I also don't get any lights on the dash even though its running decat? only shows a code in VCDS
