Definitely not going to be getting any different injectors.

Yes, but the news is not good. Basically, the turbo is too big to be subdued by Jabbasport, so I'm going to be letting Allards check the turbo is OK first (it was overboosting to well over 2.5 bar and would not stop doing it) and most likely get them to map it.
turbo size has nothing to do with its pressure,,, normally a big turbo can sustain a bigger pressure yes but this doesn't mean that it can't boost less,,,
It's confusing for me too. But I'm going to let the people who designed the turbo/cam and much else on my car, do the mapping. Like I've said elsewhere, it's sad for me as I've been a customer of Jabba for some time, but it seems this TDI kit is too specialist even for them.

Itsn't it true though Jason that when the tuner at Jabba put the basic map back into the car it would also show this same characteristic spiking it did with a more aggressive fuel map..........leaning towards the fact that something was coherently wrong with some part of the hardware.....and not the map.
Requested boost and what the n75 duty cycle were on par....its just that every time a certain amount of fuel was added the wild spiking would begin......many people on tdiclub have found this spiking to be so with and especially more so on the vnt2056's.....which is happy at around 1.6 bar but has soon has more fuel in introduced they over speed......and if too much is used down low at iq "let the surging biggin"
Try adjusting the actuator rod so its longer = slower spooling will accur but more controlerable boost will be possible when more fuel is added.....up to a point.
P.S........And i too know what its like when it doen't work out

So what your saying is when Jabba put the basic map back on to the car (which was written for the VT2 turbo with stock cam ) which is now running a much bigger VT5 turbo and a different profile cam the car wasn`t running properly so it has to be hardware problems not the fact that the map was designed for a totally different turbo and cam set up
. So you would expect Jason's old map to run with a totally different setup properly with no problems ?Oh yeah by the way Steve my car is a fast luxury road car not a stripped out tin shell drag car, the two are totally different types of machine designed for different purposes. Try and get that into your thick head.

Jason when we finally meet up you will definetly be the one with the thick head!!
If the so called vt5 map was put back as you have implied it shouldn't have had the effect on the new turbo that it did even with the so called higher profiled cam...........how much more fuel would you think the cam gives Mike over stock and at what rpm's ........lets say it was 10% more which along side the vt5 fuel map wouldn't / shouldn't have coursed what happened to happen........with said vnt5 setup a much more aggressive fuel map can be achieved............so where does that leave the hardware
.
I'm the one trying to be peacekeeper here. 
Whatever Jabba did they could not control the overboost - my old map couldn't and any combination they tried couldn't. I just put this down to jabba's software not having the "gift", whereas it looks likely Allards/Miguel's system will do this for me. The only basis I have to come to this conclusion is due to another local VT5 running car which I've seen perform "bloody well!" with their mapping.
Tis a shame that Jabba cant get to grips with the VT5 on Jasons car. Maybe its down to Jabba not knowing specs of turbo e.g compressor map etc.
They are my remapper of choice too and was going to Jabba to get my VT5 done soon by Mike.
Maybe better to leave the map to the people who designed and built the turbo after all.
Dont really understand why some on here seem to be quite anti-Allard. Jabba are of course very experienced in mapping and tuning bigger turbo petrol cars but maybe some aspects of tuning diesels with big turbos are beyond them? just a thought.

I / we are not anti anyone and when you say your going to let the people who made / designed / ie Allard this is not exactly true especially if the turbo in question is a vnt2056......stock Audi A4/A6 V6 tdi unit.
Some of these turbo's do sometimes have the actuator arms set wrong from the off.......this is what i would investigate first and also the vane mechanism.

Listen Mike since you have a captive audience over here and every one thinks the sun shine out of we all know what.......and poo poo what advice i give or suggestions i make....why not give us your 10pence worth in what you think could be the root course of Jasons problems........and before you say your not technical about these motors.......how would you be qualified to poo poo what i'm talking about / am saying

How come you know so much about the Allard turbos? You had previously suggested that the Allard turbos were VNT17 based and now you are suggesting my VT5 is a stock V6 TDi unit?

My point at the time was to suggest it was a vnt17 because it amuses me to think that people pay for something they don't really know what there paying for...........FabiaTDI do you know exactly what turbo you have and the spec of that turbo!!!
You are not really answering the question though are you? How come you say you know so much about Allards turbos?
I do know some of the specs of my particular turbo, yes.
I seriously doubt many people out there who have purchased hybrid turbos be it for a diesel or a petrol from whichever tuner, know the exact specs of the turbo they have bought. Surely the turbo is bought to perform to a specific level and understandably be it Allard, Turbodynamics, JBS etc etc they are not going to go round giving their exact turbo spec build secrets away are they?

Ok then lol..
Although from a couple of things you have now said in this thread, it is clear that you know far less about the VT5 than you claim to know.
