Hi Cadman, I've been a mechanic / auto electrician for 21 years.

I have done lot of exhaust back pressure testing over the years.

When the customer complains vehicle won't go over 30mph, it won't rev up.

The test that is carried out is to remove the upstream O2 sensor and insert vacuum gauge.

The results shown in the previous video show me that the gauge is reading back pressure.

Simple way to prove it.

a) fit a vacuum / pressure boost gauge
b) unhook the compressor

I'm giving tips to the youtuber on his setup.

I have already advised this.

I'm like you, waiting for the video.

Something else happened that we were not expecting.

A video is being done to show that too.

Hopefully I'll have something to show today.
