I have had my car on the diagnostics and confermed it is running 1 bar boost
I have fitted the pipe on my boost gauge and it doesn't seem quit right it shoots al the way to 20 psi then falls back to around 15 but in 4 th if you floor it ,it just bounces off 20 I have a vid but don't no how to put it up
Don't no if it is just because it is a cheap gauge
