Tiguan IS38 and Big turbo upgrades

[Melbourne_Tiggy]

A not so old one? Lol
R33 runs Teflon Speedflow lines front to back, 2x Walbro 450L pumps, 1x Destchwerks DW200 lift pump, twin solid state relays, 60 micron pre filter, 10 micron filter and an Aftermarket Industries SPR400 surge tank.

Stupidity? Yeah.. Sometimes I wished I just bought a 335i BMW instead lol.

Anyhow, went off topic lol

My brother has a 335, those N54 TT engines are so underrated / detuned. Highly recommended for modding with MHD and very cheap to get an overseas tune sent to you for both ECU and TCU. The ZF gearbox is pretty strong also and has a number of special tunes and continuing development you can get for a couple of bills.

Plus less unwanted attention on the road...

But back to Tiguan turbo upgrades. I'm in the process of getting some pricing through my tuner and also separately for a TTE470/475. Just waiting to see who comes back with the best price.

Exciting! There is still time to get it under the tree for Christmas Day.

What supporting mods are you thinking of getting ?

Intake, intercooler, DP - usual suspects

Are you going with RD Technik?

Are you going with RD Technik?

Yes. This is the best option for me locally for custom tuning.

You could take a drive to Melb to see Alex from Underground Performance, I’ve heard many good things and he’s tuned a number of hybrid turbo vws (they recommend Snailturbo). They have a dyno in his shop to do before and after runs and calibration/customisation of the tune. Has RD done any IS38 hybrids? Any charts or data?

I’ve been down the track of driving to Melbourne for tuning in the past and I’m not going down this path again. If there’s ever any issues with the tune or you want it modified in some way it becomes a complete nightmare. You either have to go for another drive or put your car on a truck.

UGP are the local agents for Snailturbo so that is what they use/recommend. I don’t have an issue with the product it’s more the support and regular servicing/maintenance that is the issue.

That’s why I’m going with Haines Mechanical/RD Technik. I can get everything done at the 1 workshop from fitting all parts, tuning and regular servicing and it’s the same mechanic that does all the work.

The other 1 stop shop options locally are APR dealers (limited upgrade options with expensive hardware) or Racingline OEM+ but then again limited packages and the dealer is on the other side of town/near dealership rates for servicing. UGP have just put a dealer here but I wouldn’t take my car there for regular servicing as they’re a “general“ workshop rather than being a VAG specialist. Plus not all have options for DSG tuning (which you have found out).

So when it’s all boiled down there’s only really one place I’d take my car anyway.

I could understand it would be a nightmare if you don’t have local technical capability and support, agree this is critical for any build.

You could get the spanner work done at Haines and then get a custom tune elsewhere, however it’s probably good to do everything at the same place so they are accountable for the outcome.

In terms of servicing, Haines capped price serving for interval servicing looks like a bargain. If they are using liquid moly or motul that’s a good price.

DSG options are very limited and in AU not a lot of specilists, I’ll let you know how I go with TVS.....

Yes Haines use Motul and there's a big plus for doing everything under the one roof as 100% accountability with the workshop. You don't get one workshop blaming the other workshop for poor workmanship and be the guy stuck in the middle.

RD Technik will do a remote dyno session so it will get dyno tuned and they are one of the few people that write DSG files locally to match with your torque/power curve so that gear changes keep you in the power band. Plus can add in crackle maps and DSG farts to customer preference
