Remapping a PD140

[vRS_Pagey]

Looking to organise a remap for the GT in the next few days, but I am concerned about the apparent weak turbo in the PD140, I know a couple of people who have had major issues, one of them had to replace the turbo with a hybrid along with the downpipe and cat!  

I would appreciate any advice members have on this subject, although the standard engine has reasonable power it feels truely gutless after driving the vRS.  I understand that even mapped it will be no comparsion, but it will still be a massive improvement over standard.  The map will be done by Shark Performance and estimated power will be between 170-180 bhp and torque around the 300lb/ft mark, it will also be switchable via their STS unit.

Thanks in advance, Lee.

Most failures I have seen have been on standard cars or cars mapped by cheap mobile tuners, the mapping itself wont cause turbo failure if done correctly.

Stage 1 on the PD140 should only raises boost slightly, mostly to increase airflow to eliminate smoke to get a better AFR. Most of the actual performance gain comes from altering fuelling maps and torque limiters.

The turbos are the weakest part of the pd140 engine.My first turbo was going before the first map went on mine..I was told Vw used the turbo of the mk4 130 in the early mk5 like mine but they changed the turbo in 2006..As Dave says if the map is don't right it won't cause you any issues

I had my 58' plate GT-Sport 140 remapped with Revo when I had it. I ran it for 12 months with no problem but 3 months after I sold it the new owner had to replace the turbo

Also be prepared to drive around in a mobile smoke machine as the amount of soot that comes out will increase quite a bit

Mine smokes very little and hardly any with pdt map on

Thanks for the replies guys, interesting comment about the smoke, I was lead to believe that it wouldn't be any different, I will be fitting a EGR by-pass though?!

I wasn't expecting an increase myself but blooming heck I was suprised But with that in mind I did replace the down turned pipes with a straight exit Miltek so this probably made it more noticable.

yes, removing the cat can increase the visible smoke.

As Maxitrol said, he saw very little smoke with our map, thats the way it should be. too much smoke = too much fuel or not enough airflow (boost).

What sort of gains do you typically see with your map?

I dont think bluefin, Revo make any modifications to boost pressure or if they do they are very little. 

send superchips a mail and ask their opinion

heres one of the most recent 2.0 10PD we have tuned: http://www.dyno-tuning.co.uk/gallery/audiA4140BHP20d.htm

That is a very similar graph to what I've seen from Shark, very impressive and smooth power curve peaking at 3500rpm rather than 2500rpm on the standard map.  If it wasn't for the excellent deal they are offering and the STS I would come and see you.

This is the 3rd turbo on my 140pd but this one is now an hybrid so hoping its a lot stronger On Dave's(PDT) rollers it saw 207hp with a stage 1 map but Ill be letting Dave loose on it once I receive my ECU back from Kula.

The amount of smoke is the same has standard maybe less so i'm happy

What mileage has yours done?  I would hope your driving style is 'spirited'........

Out of interest, what would a hybrid set me back, and is it a conversion a normal mechanic could undertake or is it specialized work?

My car has done 105k now, still on original everything, had it remapped a month ago by a decent tuning company to 190bhp and 300lb ft torque, best thing I did, if anything goes it goes as for mileage mine has done I'm not gonna worry too much, just an excuse to upgrade for me.
