Boost levels at crusing speed

[threedogs]

Is your IC oily, at all.
Mine sits @ 10PSI doing 100 kph constantly

Threedogs - I checked the intercooler had a small amount of oil in it.
I now have the new intercooler and catch can installed as well as the 3" exhaust and it's still doing it but climbing up to 20 psi now??? One thing have noticed on my ultra gauge is when the engine load is around 56% - 58% is when the boost wants to heads north?? The chip goes in Tuesday so I'll see if that changes any thing otherwise back to Nissan I go!!!

If you block your EGR, your boost level may rise even more. Install a Dawes valve, at the least, and your problems will go for ever. Add a needle valve into the mix and you will have the power to make your CRD go even better.

I thought the crd needed a 10mm hole in it Or it will throw error codes or limp mode.

I haven't come across one yet. Sold around 100 plates in the last five or so months and no reports yet. But having said that. There is a first time for everything. Being a CRD I am surprised really.

Crd sometimes throw egr flow error code. Easily cleared with scangauge or similar and definitely does not go into limp mode.

[threedogs]

The ECU on the CRD is more tolerant of higher boost levels,
This Chip you mention is it after market and Nissan are fitting it,??
With the IC being oily it may mean its leaking, so my point being how can it hold boost.?

[mundlich69]

Three dogs its a tunit chip and not installed by nissan, but the chip has made no difference as the issue is still there. I have booked it back into Nissan and I reckon its due to engine load certain speeds as when I sit on 120 boost sits happy at 12psi, drop down in speed and either using accelerator or cruise control boost will climb up to 20psi at a certain % of engine load??

Have you blocked the correct end of the EGR pipe ???
Disconnect your battery for 1/2 an hour

[mundlich69]

Disconnected the battery for hours and still the same. Took it back to Nissan again! Still no answer there still waiting to hear back from Nissan tech. In the meantime I've brought a Dawes valve at least I know that sort the issue once an for all!
