New Larger Intercooler TD5 D2

Increase max boost = shorten rod

Decrease max boost = longer rod

pull the hose of that goes to the wastegate modulator diaphram.
if this dosent make a difference you have a problem.

if it works you will over boost, the car will still drive but the fuel map will go to a defult setting, so the car wont be real responsive. turn the engine off and re start, that will reset the map.

marcel showed me this trick ages ago.

cheers phil

yup did mine like this ages ago, while on the phone to DW in Alice.

Pull the hose off the turbo, went into over boost at 1.3 Bar so shortened the rod to give a max of about 1.25 Bar - No Worries.
