Kick, I`m going to buy a vacuum pressure tester in the coming weeks. I`ll add a T plug in the vacuum line just before the egr and will install the tester on the windshield to be able to see it when sit in the driver side.

I would also like to install a compression tester to check live the pressure that goes from exhaust to MOD. So I would be able to check both lives. However I have to fix my exhaust first as it isn`t air tight.

I was almost thinking of installing two gauges somewhere in the Dashboard to be able to have a look at it anytime. would it be a bad idea ?
