Bet thats one of the weirdest VW diesel dyno plots around.
Notice how much more like a petrol car's the power curve is.
I'm a little disappointed (but not surprised) at the low peak torque value. I really put that down to lag - its easy to see the turbo really doesnt wake up until 3000rpm. But then, its also pretty obvious that it does reasonably well up to 4700, which is much higher than I thought it would be worth revving to.
I will now look at doing some "passive" mods to improve hhe low down torque - maybe some exhaust modifications (delete muffler and maybe make a new down pipe for earlier spool) and I really want to get in and make an intake manifold with nice long runners, because the stock manifold is absolute trash. That, I reckon, could make a big difference overall, and with a little extra fueling, i don't see why an extra 10-20hp isn't available just with those mods.
I've gotta say though, its nice to put a number to my efforts so far - and given that this beast was 74hp (at the flywheel) when it rolled off the production line 16 years ago, and now 253,000km later it can make 110hp at the wheels, I'm pretty happy
