  I didn't upgrade the inter-cooler 

 

Considering the development of this upgrade was based on a golf, i think you're asking for trouble going without one newbie.... if i may be so bold sir....

Why would the Superb need it more than say a Golf R estate that weighs roughly the same considering they are both running the same stock unit?

The upgrade of the intercooler can be beneficial depending on how hard the map is pushing and the environment, it is a supportive upgrade that ensures full performance is achieved even in tougher conditions but it's far from the cornerstone of any map's development. Worst case I might be leaving some performance on the table especially when temperatures rise but as long as the car runs as strong and the logs are as clear as they've been so far there's no reason to assume I would benefit from one, at least from a safety perspective.

I don't chase every last horse any more but I do always keep an eye on how the engine's running and run my own logs regardless of what each tuner claims. The other night, the car was hitting consistent times in repeated pulls (must have been 7 or 8) over the course of a 30min drive, no heat-soak or reduced ignition timing whatsoever. It was a cold night yes but that was the most demanding driving scenario I'd be putting the car through and it performed flawlessly. I also have access to Ethanol in the fuel stations here and traditionally, especially in the summer I usually do run a mix of up to E15-E20 if I see some knocking so I will keep an eye of-course but from the way things are at the moment, it would need quite a change to justify the need to upgrade it. Not saying it's impossible, just that the signs are so far promising.

In any case, not upgrading the intercooler is in no way equivalent to say running a stage 2 map without an upgraded downpipe (that's how I interpreted your comment ) which is a big no-no. REVO would of-course recommend it as it is an extra safety for smooth operation under all possible climates (and a considerable revenue to them) but I'm lucky to be somewhere where ambient temps don't get too high or for prolonged periods of time so I could get away if the map does not turn out to be too extreme (which REVO maps are not known for being as such in general). Let's not forget this is not a real stage 2 anyway as it runs on the stock GPF downpipe... rather a maxed out stage 1.

I can confirm the Revo Stage1 is amazing! JB4 was good, but Revo is a different league. I can't believe what a simple software update can do with these engines, that's how those DNUA should come from the factory:)

Next step is TVS Stage 2+ for the box. 

Thanks @newbie69 for all the advises and courage to be the first and share your experience!

In short, prevention is better than a cure. That's my thinking.

As a general principle I totally agree, but this case is far from preventing any sickness as I explained a couple posts above, apart from broken feelings from lost races (for whoever is into that...)

Worst that can happen is continuous heat soak and power cutting but considering my given involvement with monitoring how the car runs, logging times and data, chances are pretty slim it will un-noticed if it shows up later. And if it does, the solution is straight-forward, it's just that the current conditions don't seem to call for that sort of upgrade at all. REVO probably didn't set up the map for the favourable cold Swedish climate and an unleaded-ethanol mix that helps things but, i'd guess, for tougher conditions.

If we seriously want to talk prevention though, upgrading the turbo in these cars when running stage 2 is a is much more crucial upgrade, that could also save several $$$$ of damage in the worst case scenario. Have you upgraded yours?! 

This is something I am toying with currently, simply because this is our daily car and also it is planned to cover some big mileage this year so if the IS38 turbo lottery happens to show my name at some point, being off the road is not a good scenario at all. In fact, as we speak this is an upgrade with a much higher probability of happening than an intercooler upgrade despite the higher cost.

These guys are also providing an "upgrade" to the bearing and guarantee reliability and longevity @400 ps. (without requiring extra calbration/remap)

I'm seriously considering a precaution step in that direction. Even though I'm only stage 1 it's a bit unpleasant to be left in the middle of nowhere with blown turbo, during my summer holiday trip. Plus - that's a good foundation for Revo Stage2 performance pack:)

Nice one. Upgrading your own turbo and in particular the parts of it that are prone to failing is probably what many people are after who don't want to go to the next level of a true stage 3, but would like to eliminate the biggest risk of something going bad and taking (possibly) other more expensive stuff with it on its way out. I agree that stage 1 or 2 does not alter the situation too much in terms of potential failure. Already at stage 1 the turbo is working at 33% increased boost.

I was considering LM turbocharger upgrades but they are twice as expensive as they are also bigger and make more power plus other parts would have to be upgraded so it would be a proper stage 3 and I don't want to go much further than 400ps on this car really.

But 700EUR for upgrading the core is really a small cost when taking into account the cost of other typical upgrades and the importance of the turbo longevity. I might look into the TTE upgrade more seriously, the thing is I am not sure if i could tackle the work myself this time, and I don't have any workshops I can trust for this type of job nearby. Otherwise the cost is really insignificant for the benefits it brings. Just take a look at the "blown turbo" thread and the continuing trouble the OP is going through with his car...

The REVO dealer in Sofia is also a TTE dealer, so I plan on using their services on turbo removal/installation.

That's very convenient actually. GPF stage 2 does not require a downpipe, (well at least the stage 2 offered by REVO, i know others have removed the GPF and run even stronger times but anyway) so you can also consider it as a cost that you'd normally have paid to go pre-GPF stage 2...

Yep, I know that.

I'm waiting for the local TVS dealer to be available. Once I map my DQ381 box and all is fine - then in March I'll probably do the TTE Turbo upgrade + Revo Stage 2 Performance pack (software, cooler, pipes and intake system). 

If I have some news - I'll post them here.

Hi guys! Is there any same type of topic but for 1.8tsi engine with dq250?

I'm wondering if someone did the stage 1 at a high mileage...~183k km/114k miles

Thanks
