Guys, I know this has been asked millions of times before but I just wanted to check something!
My stock GTI is peaking at 16 PSI and tailing off to around 13.5 PSI. Sounds a bit high from what I have read but I may be wrong? I'm not complaining at all! Car runs very well, 2007 BWA engine with 42k.
Sound about right or higher boost than expected? No codes within the ECU.
Thanks
