Stage 1 ZD30 GU Patrol
The ZD30 (3 litre) before and after figures with only the DP Chip fitted. This vehicle used in this run,
was an automatic, and second gear was used, as the vehicle kept on kicking down.

Stage 1 GU TD42T Patrol
We have worked long and hard working out the best basic settings on the TD42T configuration.
Power and Torque figures may differ between early and late vehicles as later model Patrols produce
more power in standard trim.

Stage 2 GU TD42T
This is our most common upgrade. We fit a full 3" mandrel bent exhaust system including
dump pipe, reset boost pressure, injection pump timing and fuel delivery levels to Diesel-Tec specs.
This makes the vehicle a much better, easier vehicle to drive, with great low down torque for towing,
better fuel economy and no excessive exhaust note or drumming.

Stage 3 GU 4.2 TD42T.
The owner wanted more power than usual upgrades, having tried our Stage 2 setup.
So we matched a Garret ball bearing turbo to suit his needs, made the necessary pipe work to make it
all fit and retuned to suit the extra air flow. This now uses less boost than the original turbo,
has lower exhaust gas temperatures, better fuel economy as driven the same as before,
but provides better low down performance than original with more mid to top end power and torque.
Power and torque curves are flatter as the turbo is much more efficient in design.
