ok thanks for the info Tony.

So the scangauge would be the way to go instead of the Pyro.

Thanks.

Thanks again Tony.

Will sort something out soon.

I've noticed that on the 2.8, the turbo spools up about 300rpm earlier, so it should be about the same on the ZD 30 DI.

Hi Ferret, hows this cold weather we are having here in Mandurah? lol
Anyway that was a little off-topic.

I might just fit the old style (analogue) gauges, ie. Boost & Pyro. The only thing is trying to DIY!

Just read up on the exchange that Taipan XP does "3L Patrol Intercooler Elbow".

Have a look on Ebay Adrian, you should find what you need , an egt and boost gauge is all you would need, you could wind the VNT back a bit till you get it sorted,
Tony's advice is good advice.
It's warm in the workshop by the way.
cheers Rod.

Thanks again for the info/help guys. Installed a Chip Express unit today which made a huge difference, but definitely need the gauges as said.

For all who are interested check out egauges.com

I know they are in the states but they have a full range of Auto Meter and VDO metric gauges to suit all applications. Even with the shipping its still cheaper than sourcing boost and pyros here and FedEx shipping gets them here in about 5 days.

To CoR I have the same chip and I cant be happier, just need to find time to fit the other mods.

I have been reading this information about ERG valves and Boost gauges. I started by getting a boost gauge and checking my boost prior to any mods being done. I have the ZD30 engine. I had cylinder head replaced 15000k's ago, cracked between cyl3-4. 155000 on the clock today.
I monitored the boost in city and country driving. I then installed the blanking plate for the EGR and this increased my boost by 4-5 PSI.
I then adjusted the boost back to 10 PSI at 2600RPM in 5th gear (as it was before) I have noticed there is an improvement in my power available. I have also installed a catch can to remove any oil carry over into the intercooler.
I have not installed a larger exhaust system, but I have installed a chip and went through the same process to ensure over boosting would not be a problem.

My reason for writing all this is because I would like to thank all the people that have worked on this and have put there thoughts to this in an effort to improve reliability of the trol. I work in the diesel engine/generator business and I am surprised a thing like the EGR can reduce the reliability on a diesel engine.

Again thanks all

Guys

Interesting feedback, I thought I'd add some experiences. My 2010 CRD Patrol is fitted with the Taipan chip and 3 inch exhaust. I have a pyro and EGT gauge as well and found that with the chip the old girl would sing, right up until the time I was towing (at that time a 1.6T Jayco Camper) thats when the fun started with boost peaking to 25 psi and the ECU kicking me into limp home mode.... 1ST and 2ND GEAR ONLY ! I spoke to Taipan again and got a dawes value fitted and this limited my boost down to 17psi which doesn't activitate the limp home mode even now towing my 2.5T Jayco Expanda. My EGTs normally don't go above 550C however it has gone up to 680 odd when pulling 5.5t (truck and Van) up hills. From some of the feedback from Andrew at Berrima Diesel in the 4wd Custom letters that the 650C is not that unusal for the CRDs. In short if you dabble with the donk, put the gauages and valves on and save yourself some fun with the limp home functionality strikes.
Ferret I would be keen to see if you still have any EGR (with small hole) plates for sale.

Cheers

Yep I can do the hole, but are you sure you want to do that?
Cheers Rod.
