Tiguan IS38 and Big turbo upgrades

Stage 1 ECU tune and E85 map is just around the corner.

I can tell you that a DP, injectors and E85 is all you need with an RS3 to turn it into a serious weapon.

The guy who own the workshop that I get my car serviced at has one and it’s one hell of a loan car I can tell you!!!

Impressive! But I have to draw the line somewhere. Stage 1 tune and E85 is best bang for buck at this point, 404kw is ridiculously fun and cost effective, car runs like it was meant for E85. As much as I want to get a downpipe they are 2k alone and it’s on the list but so is living within the means. I’d love to custom tune but I have to draw the line. Just driving this car stock is so much fun, us as tuners are always looking for more but I will have to keep a lid on it for the time being. 👍

Might be able to find a quality exhaust shop to custom build a downpipe for a lot less. The place that made one for my Tig. ($1000 fitted) has done RS3’s.

Nice work on the RS3. My bro in law got one. I drove it standard with 100kms on the clock and even that impressed me. Great car. The mods **** in due time.

Ps I’m loving my Tiguan now with the tune. Exactly what they should have sold. A real R.

Sorry to hijack this thread again guys but it’s something you Tig owners might need to keep in mind considering they run a version of the DQ500 or even the same, however this DQ500 in the RS3 felt and sounded vastly different, no mechanical clunks and gear changes that were on point.

My RS3 has just gone in for an interim service, something I do with all of my cars every 7500klms. Although the RS3 wasn’t due, I got it done for peace of mind. Anyone who has followed my comments on the DQ500 in my Tig will know I went through two gearboxes (leaking bevel box) and both replaced under warranty.

I can report that I’ve now had THREE gearbox failures. All three were during unmodded phases and the RS3 I just purchased with 15k on the clock has a leak at the bevel box. It has never been modded (checked with both Audi with its VIN and OBD-11 and the two most well known ECU upgrade companies) and both reported definitely no bolt on footprints and zero ECU footprints, as did Audi.

That’s three failures, either I am the most unlucky person in the world to ever own a DQ500 or there are serious issues with the gearbox. Fortunately my car still has a years worth of warranty but for you guys owning Tigs with DQ500 trannys I suggest you get it checked out by a third party VW approved mechanic. The reason I suggest this is because VW initially told me there was no issue with the box and it was normal, once I showed them the report from my VW approved mechanic they changed their tune and said yes there is a problem and replaced the gearbox.

I will add that the DQ500 in my RS3 made zero noises unlike my Tig gearbox did, it was quiet as a mouse and changed gears like a demon. I had absolutely no idea there was any issue at all with the gearbox both mechanically or through the clunky downshift sounds I’d previously heard.

Just a heads up guys, I’d hate to see a car out of warranty get stung with a replacement at full charge. Get it checked out for peace of mind. My cars going in next week. Best of luck.

Had a run in Mexico with a GLC43 AMG. Went from behind him at the lights around and 2-3 cars infront. At the next set of lights he looked totally confused as to how hes AMG was beaten by a VW..

Not as impressive as it sounds really TBH. Lots of factors in it. I test drove a GLC43 and its quite sluggish in anything but sport+ mode. Most drivers (from my experience with Merc drivers) would not know how to change from normal to sport ... With launch control properly used, the GLC43 is a 4.9s car, not quite as quick a modded Tig. HOWEVER, with only a simple tune ($2000) on the GLC it makes ~360kw 650NM and does a 3.5s 0-100 ...

If you compare what you spent on the Stg 3 Tigs (close to 90K I'd bet) you can have a 3.5s GLC43 that's a few years old with all the delectable AMG extras plus handling and end up spending about the same really As a bonus you won't have to deal with any DSG issues either ....

I might actually do this 1 day if I could live with the atrocious ride on Aussie roads

No way it costs 90k to make a stage 3 Tig, base cost plus mods..

Probably not, might be closer to ~$70K , but I now see you can actually get into a low km 2018 GLC43 for less than $80K .... The standard extras in that plus the massive future potential is worth so much more than just a $10K difference.

Don't get me wrong, I certainly have taken many many mid-range cars and made them perform as well (and better) than a large number of performance cars (1st Stg 2 Tiguan Mk1 in Australia was mine for instance and it was a base 125kw to begin with) and always (and still do) loved that.

Really appreciate the superior engineering (and massive future potential) that goes into the actual performance models though.

43 and 53 are not real AMG's some would say.

To be a real AMG needs to have a hand built engine.

The comments here and on other threads on DSG problems are starting to pique my interest. It's been hard to gauge from what I've read if it is a persistent fundamental issue or a combination of really bad luck for some owners, and some melodramatic reporting.

From the posts I've read VW seems willing to replace DSGs for the reasonable behaving owners who had accurately and politely worked through problems with them.

Could some of the more senior (IS38 / tuned car) owners here comment on this from the perspective of playing lotto on a new tig, as well as how you think VW would handle bringing a modded car in with these type of issues? Are DSG tunes detectable, and is it a safe bet to avoid them for the first year / x thousand kms if you would need to make a claim on the box? Any other comments.

I am new to VW but other brands that I have bought and modded new cars from have helped me out on warranty claims that were not directly related to the mods, including big HP cars with turbo kits and e85 tunes. Most of the comments here have been that VW would just instantly turn down any warranty claim on a modded car, but I am wondering if that is actually the case or just assumption.

Hi SouthTig, I wouldn’t count myself as “senior” based on age or forum participation. However, in reference to your question the Dq500 has held up well on my IS38 Tig with TVS TCU tune. I’m at nearly 30k km. I had all the reported clunking sounds with the stock TCU the tune did solve these issues for me. In relation to warranty I suspect if VW see/detect the mods they would not warranty the box. Pay to play as they say....

Tiguan IS38 and Big turbo upgrades

Don’t get the R600 silicon intake hose. It doesn’t fit well in the Tiguan. Save yourself $275

I’ve got the APR intercooler on the Golf R and the CTS on the Tiguan R. Both are fantastic quality. I really like them both. Both made in quality locations... which isn’t a game changer but just like I bought a VW to get something made in Germany in the Tiguan I did the same with the intercooler.

Same with the DPs. The CTS one has the cast tops like the APR gear. Can’t go wrong with either.

Would love to know what some of those items you are getting, do, such as:


NGK racing 7437-9 plugs 275
custom tune inc. DSG 1200 (who does this? And so expensive for a gearbox tune!!)
APR ignition coils 75 ??
TVS stage II+ gearbox 1200 ??
Generic catch can 500 ??

Can someone shed light on experience or gains or even just joy of the above

I don't think I need to upgrade the intercooler. I won't be tracking the car or focused on top end power and on past cars a bigger fmic has led to less throttle response than the stock one.

I thought the same. But what my tuner was saying was that a lot of the higher horsepower number cars you see are not repeatable numbers back to back, due to heat soaking. The stock one is truly tiny. It’s smaller than a stock R cooler for example.

My throttle response actually stayed the same and the car made substantially more power across the entire power curve. I went from 186KWs to 220KWs with the FMIC installed and the car made that power on a 32.5degree day 5 runs in a row it was incredible. It’s also a safe tune that’s reliable as I didn’t want to wring the motors neck, just wanted clean reliable power.

It’s not just the cooling the std cooler is actually a airflow bottle neck on the Tiguan.

I experienced exactly the same thing with my gen1 125TSI Tiguan when I was at stage 2. I was struggling to make more than mid 140's kwaw and then upgraded to a Golf R intercooler and straight away I was in mid 150's where the car should have been. I probably could/should have gone a bit bigger, however the parts were the right price (=free) and it just took me some time to fit it.

The stock intercoolers in these cars end up being quite restrictive at higher power levels so they really need to be upgraded otherwise there's too much restriction and you just can't get the airflow through the intercooler that the engine requires. Heat soak is another reason but if you're chasing power you have to get rid of the big restriction first.
