Hunting for more power on a W123 1982 Mercedes 300D Om617 Turbo diesel. First steps to HP!

My car has unreal low end power after the injector nozzle upgrade, but it falls on its face right when it should be coming alive with boost. I walk through the first things you should check if you have one of these cars and it seems low on power, or you buy one of these amazing machines and are disappointed with the performance. Key points in video: 0:00 Introduction 0:32 Fuel = Power, Check your Fuel filters! 2:10 What your Primary filter looks like 2:40 Secondary filter 4:40 Air induction system 4:56 The Youtube 5:08 Turbo 5:40 Banjo fitting on Manifold 6:10 Overboost solenoid 6:58 ALDA 8:05 Testing Overboost valve 9:35 Remove manifold banjo and clean hose and fittings 10:58 Bypassed overboost solenoid for testing 12:00 Conclusion First on the list is Fuel Filters! Primary filter: https://amzn.to/374N6I9 Secondary filter: https://amzn.to/2ZbxO1g From there since both of my filters were done very recently (I changed them right before I did the injectors, it was lacking top end power, so I changed them then decided to investigate the injectors) We move on to the intake charge side. Specifically the Overboost solenoid and ALDA lines, these very commonly get plugged with soot from the EGR, so we clean those banjo bolts out and bypass the overboost solenoid. Then I take it on a test drive, sadly it still lacks power above 2000 rpm, Next video on this car will be removing the tank strainer, as its my next suspect.
