With all you've got on you should be able to exceed that quite easily.

Get an EGT gauge Muppet, you might not be wanting to repeat such a feat!!

I don't make a habit of it, quite the opposite
Mate had a long straight road, wanted to see how it handled it
No problems at all, a Td5 should certainly be able to handle 130...

Agreed mate, the humble TD5 is a cracker (no pun intended!) of a motor capable of some impressive numbers. Some of the things mine has done with 2300kg worth of van behind it still amazes me.

On the money there mate, it's a top donk.
Coming back to the OP, if the MAF has stayed the same then going off what people say, when they're replaced/cleaned the outcome is quite remarkable.
Running a Td5 at upwards of 130Km/h for sustained periods or up hills might not be a good idea (if you like your pistons to remain solid ) but it should still be able to get there.
Good luck OP, every time I read about the VNT kits, I think I drool a little

Hi all, I am now in a position to remap at will having just done the NNN ecu swap with a map from Td5inside and as yet have not had a chance to take it for a decent run until this morning when I will be travelling home to Caboolture from Miles on r&r.

I will be watching the exhaust temps with interest very close.

Before I came back out here to work the vehicle developed a bit of a hiccup/pause/hesitation when taking off and on the drive out it felt sluggish/doughy and so far the NNN with new map has not changed this. Fuel pump anyone, maybe?

Cheers,
Mike

Possible TPS issue? Does it do it only at initial acceleration or acceleration from any speed? If it does not hesitate when using the cruise control it maybe something to check.

Could it possibly be your boost box. I have a vnt fitted and my boost box failed, producing a miss when boost went over about 18psi. Trouble shooter it by disconnecting the box and did same thing. Replaced it and all happy again.

Hi all, sorry for the delay, just got back from camping.

Well I towed the camper (about 1.7 tonne) over some very hilly and windy roads getting to and from Levuka and I can now say that there is definitely something wrong with the boost box or the turbo boost control needs adjusting.

I was watching the boost gauge and it was spiking to 22psi at times when kicking down hard and when taking off quickly.

I will have to contact manufacturer to ask if there is a way to test it on the bench.
