Power loss after bosch pump conversion

[Gmguy]

Hi everyone,

I have recently done a bosch conversion on a 1997 2.5 td,

Engine starts perfect, is a bit noiser than before but that is to be expected, the main issue im having is it is probably 1/3 down on power compared to the epic (when not in limp mode lol)

When fitting the pump i did advance it about half of the pin hole 4 or so mm.

Is there anything else that can be done to get a bit more power out of it, particullay noticeable between 2 - 3000 when the turbo should be in full swing

Turn the fueling up

To increase turbo engine power across the entire RPM range, increase the cyclic delivery, or "fueling," as they say here.
To increase power at low RPMs, which adds a special driving pleasure, you need to tighten the hydraulic corrector screw on the pump's mushroom cap.
I have a homemade turbo engine and two high-pressure fuel pumps—a regular Bosch 144 and a turbo Bosch 154.
And the rear axle is from a 2007 car with a very "heavy" gear ratio of 3.31:1.
A regular Bosch with the hydraulic corrector screw tightened is much more enjoyable to drive.
