JAKE BRAKES & more Horse Power. *Ends in Disappointment* ERF Restoration ep.31

Welcome to the next BIG instalment of the ERF EC11 restoration project. This is a big video I have been wanting to do for a long time, finally fitting the Jake Brake heads to the Cummins! I also get to set up the top end, resetting the tappets and injectors has made it feel much crisper and smoother. I even get it remapped so she is past the 400 horse power mark! Unfortunatly it does all end in disappointment so I will be getting part 2 where we find out what is wrong and get them working properly!
