ZD30 fuel inrichment

[pumpngo]

Hi all
I'm new to the forum and have been looking at the power up options.
I just had to replace my turbo. I did the EGR , butterfly mod and the swirl while fitting the new turbo (china charger). It goes great, but runs a bit high on boost 5 by 1500 10 by 2000 straight up wnen over 2000 16-18lb and if flogged 19lb. I'm under the impression std is 15lb , so I could do with less boost or more fuel.
Everyone seems to agree the Nav is a bit low on fuel.

So I ask the question; Has anyone used a resistor on the coolant sender?
I have done this as a mod on petrol engines with success, It changes the fuel and timing. I can't think why it won't work on the Nav.
Looking forward to your opinions.

do you have a big exhaust ?
if not the turbo may have wastegate problem ie not flowing enough.

for the fueling just chip it. i think coolant sensor would only do a minor change in fuel. the main input is throttle and boost.

Thanks.
The exhaust is std appart from smashing the cat out. I checked the pressure again with someone else watching the guage and it tops at 18.5lb but only gets there when over 4000rpm. I usually never rev it that hard so probably won't be a problem . I intend to intercool though just in case.
