I know there must be some people on here who have done it so i thought i would ask.

We have just bought a Citroen ZX TD and im told it has the same engine as the 1.9TD pugs.

Basically we want to turn the boost and fuel up for the max power we can run on the standard top mount interwarmer and im trying to find out what the settings are.

Its an M plate car so i think it should have the bosch pump but im unsure atm what turbo it will have so advise on both pumps and turbos would be good.

I have been told 18, 20 and 22psi for the boost from 3 different people and none of them were sure of the turns needed on the pump lol.


Thanks in Advance may have a crack at it tonight
