Gday all PFA Looking at installing egt and boost gauges on my 1995 4m40 Pajero as apparently they crack heads if you’re not careful. I understand that to install a pre turbo EGT gauge you have to drill the exhaust manifold, can I do this SAFELY without removing everything. E.g magnetic drill bit, etc. When installing a boost gauge and boost tap/tee, what’s the way to go about it to give me an accurate reading and ability to increase boost a bit, any advice or photos would be much appreciated. Cheers
