Tiguan IS38 and Big turbo upgrades

My drivetrain is evil, it must be punished!

I think a 7000rpm LC is in order.....that would give your drivetrain some harsh punishment!!!!

Yeap, something needs to take the brute force.....tyres are probably cheaper to replace than my transfer box (I read what happed to Ramee, that was very unfortunate). I’m hoping this iteration of the DQ500 for MQB is stronger and can hold up to more torque punishment.

So close to dipping into the 3s, yet so far. I’m not desperate enough (yet) to start doing weight reduction with passenger and rear seats, spare tyre and child seat removal......

DQ500 isn’t the issue it was as you say the transfer case that broke. Both Guy and Ramee had failures.

Hopefully in MQB this is beefed up but given there’s no issues at stock power levels they may not see the necessity.

You hope it's beefed up, considering there's a 2.5 ton towing capacity

That’s the thing with going down this modification path, you do some research to understand the limits and lessons from others. But if you are amongst the early adopters, you take on risks that a number of things could fail. It’s also good to roll your sleeves up and/or have mates who are mechanics, just in case something fails.

But, you know what, it’s highly rewarding (when mods works out), exciting, and very satisfying to “surprise” those who just see it as a family people mover.

Very true, surprise factor is awesome. As we all know, if your going to increase grip and HP a weak link will be found somewhere in the drive train. Learned a lot of hard lessons in the early days of WRX mods. Weak link was always the clutch, then you would eliminate that with a brass button jobbie. The next HP bug would bite and you would simply transfer the stress onto the next weak link. Gearbox, CV’s etc, they were expensive lessons however Japanese cars were a long way behind in comparison to today’s Euro.

With my Tig, once I can get mid to low 4 second 0-100 times and 12 second quarters it will be bottled up. Your always going to lose driveability and reliability the further you push, it’s so bloody easy to fall into the HP bug. Good thing is we can all decide how far to go before your happy......in my experience your never happy lol and always want that bit more. Knowing when to quit is personal. 👍

TVS also supply race clutches and supporting DSG tunes, however probably excessive for my IS38 level power/tq. A good TCU tune should help reduce/remove any OEM dsg drivability issues including unintended clutch wear and clunks, Id actually put the TCU tune on par with the ECU tune in terms of improving the driving experience through cleaner, faster shifts and the dsg being really responsive in D (keeping in a lower gear) rather than shifting to the highest gear for economy.

As an aside, if your goal is low 4s for 0-100 the OEM IS38 will get you there with an APR IS38 98 RON tune. If you want a bit more, a hybrid IS38 is your other option with a custom tune (I think Tigger73 is investigating this option)

That’s really good info mate. I’ve heard the same feedback regarding the TCU tune. Been looking at TVS, they seem like they are ahead of the rest especially in dual clutch tune. Appreciate the feedback, awaiting to how Tigger goes with the Hybrid. Where did you track down your IS38, did you source privately or did APR supply?

TVS definitely are market leaders for DSG tuning. Plenty of great testimonies for people who have done the TCU tune, interestingly they also do ECU tuning, however I haven’t heard anyone in AU getting the ECU tune (yet).

I sourced it second hand IS38 from an S3, it’s a revision H version which addresses the earlier version failure issues. You can source a new one for around $2k. A little while ago INASNT mentioned Peerless Automotive in VIC had two second hand ones for sale. Bang for bucks is the OEM IS38, and there quite a few IS38 GTIs, Tiguan and Skodas around the world which have done this with great results- plenty of off the shelf tunes like APR and Revo and a number of custom tuners like Etuners and Undergound Performance can tune them.

I am also very interested in seeing how Tigger73 goes with the hybrid route.

It's called Tig sleeper edition...

Help me! Lock up the door and throw away the key!!!

I haven't heard of any TVS ECU tunes... probably if someone is selling them they are likely rebadged as they're not really well-known brand.

Probably the best bang-for-buck route to head and pretty much most tuners will be able to have a file for these as it's basically a Golf R.

Interested too. I'm in the process of collecting parts. A big piece of the puzzle is about to be ordered very shortly.....

I need to stop reading this thread, really want to mod the Tiguan but I promised the wife it's staying stock lol..

Is there a way to self exclude myself from this thread? Haha

Not that I’m trying to help you be deceptive, but you could negotiate a change of downpipe and tune with the boss...........and whilst you are at it you could do the turbo swap whilst the downpipe is out.

Well just pulled the trigger on a TTE475 earlier today...

This thread just got taken up a notch....

The Franken Mumster has been resurrected in Mark 2 body now the TTE475 Tiguan....

Looking at some of the TTE turbos on other TSI engines it looks really promising, if you are getting over 500NM consistently from 3000 to 7000 RPM the Tig will take beast mode to the next level.
