Ground down the LDA pin inside the pump For more fuel delivery
Removed the white washer around the LDA pin so the pin will get more fuel
Adjusted max fuel 2.5 turns
Boost compensator 3 turns
Modified top hat
Advanced the pump by 3 degrees
got rid of the idle bar and rev bar so revved freely to 5500 ( the k03 ran out of boost by 5000 though)

Theres also more you can do, like take the head off the pump and fit a transit 2.5 11mm plunger, also take the top of the pump off to get into the govenor and make it sold and getrid of the springs, Then theres all sorts after to do,

Straight pipe, front mount using xantia/406 inlet manifold, t25turbo ( welded onto standard manifold ) and other wee bits, quite alot of dturbos over 160+bhp and 250ftlbs now, 2.0 corsa killers lol
