HOW TO: Turbo Diesel BOOST EGT GAUGES VE INJECTION PAJERO 4M40 4D45 PUMP BOOST POWER HP INCREASE

Upon research, it looks like more than 1.8 bar or 26 psi (perhaps less) can blow the old stock intercooler. So, I decided not to pass 1.65 bar. However, I didn't want my boost to be limited due to lack of carburant. My goal is to have the boost controller CONTROL BOOST...not an absence of fuel. Until a few days before this video, I had been maxing out at 1.4/1.5 bar or 20-22 psi. I then disconnected the boost controller (which was set at the most 'closed' setting) and then achieved 1.5/1.6 bar or 22-23 psi.
In this video, I remove the fuel pin diaphragm spacer, which was 5mm thick, then shaved down to 2.5mm. Immediately after removing the 'fun police' spacer the boost now consistently reaches 1.7-1.8 bar or 25/26 psi.
It's important to not that I have a 2.5" straight shot (no cat, resonator, muffler) stainless exhaust system. I have also installed a boost controller and most importantly--an EGT (exhaust gas temperature) gauge. I believe this gauge is a necessity before ANY tuning.
I may 'get deep in the weeds' or 'waffle on' in these videos, but prefer to provide any relevant detail and let the viewer fast-forward through unneeded parts or details.
