My ZD30 turbo boost pressure and EGT readings are recorded in real time while driving.
I think it's important to have these gauges to give you real time read outs, so you can see how they are performing at all times.
The EGT readings coming from my ZD30 sit around high 200's to low 300 degree's at 100kph.
Temp readings at that speed are low, which is where i want them to be.
One thing that will destroy a ZD30 is high EGT readings.
If you haven't had a gauge to show you at least the exhaust gas temperature ( EGT ) readings, have one installed and drive like you did before having this gauge installed.
You will be shocked by the high EGT readings your ZD30 is putting out.
Both the boost pressure and EGT readings are very important numbers to know.
I highly recommend that you get both gauges so you can monitor your turbo boost pressure and EGT readings.
I'm very happy with the gauge readings Im getting from my 3ltr ZD30 Nissan Patrol.
