any simple mods to get 160-170hp possibly turn up pump shim inj turbo? just hoping for some vetrans simple advice

 

Turn up the pump, there's 10-20% power available there - need to look online in MB diesel forums for details. Might get you up to 140-150hp. Little to no power is available in the injectors as long as they are spraying correctly, and at the proper pressure. Stock turbo at ~13psi should be plenty. Don't expect 160-170hp without larger elements though... $$$$...
