Mk2 Tiguan Tuning

[Psych101]

Anyone have experience with the jb4 tuning box on the mk2 tiguan that they can share (good or bad, ease of installation, power gains, maps, updates etc)?

I am considering the jb4 based on simplicity and ease of reversibility. I want to be able to return this car to stock fairly easily and am looking at mods consistent with this.

I’ve heard reasonable results from JB4. It’s definitely not as good as a flash tune but gives you 80% with the ability to go back if you need.

If you’re only wanting a moderate increase over stock it’s not a bad option. However if you’re going to want more then you’re probably better off getting a time to start with which offers more flexibility for adding hardware.

Very easy to install, noticeable 'seat of the pants' power gain and a good amount of extra shove. I'm using Map 2, haven't played much with it other than that as it has met what I was after from it. I did edit a Map 6 I found out about via the Skoda owners group which has been tested thoroughly as safe and gives some more punch over Map 2.

I'm on the fence about keeping or selling the JB4 as I may be selling off the Tiguan shortly and grabbing an Amarok or Touareg instead given we now have a Golf back in the garage...

Cheers for that. I want the full beans but don't want to go down that path on a brand new car. JB4 should keep me happy for a while and it is pretty cheap for the gains.

Might get more serious closer to end of warranty (notwithstanding jb4 technically jeopardizes warranty but it seems like a lesser risk compared to a proper ecu tune given flash counters)

What is the easiest path to keep the stock turbo and maximize performance with bolt-on mods only? What gains can you get with this approach as well?

I want to be able to revert to stock fairly easily including the exhaust and fake outlets.

It depends on what your motivation is - whether to return to stock for warranty or for sale.

The easiest thing to return to stock is a stage 1 tune (no hardware) as this is simply an ECU reflash.

As soon as you start installing hardware it becomes more difficult (and costly) to return to stock.

Intake is relatively simple - as install can be done from the top of the engine bay in 30 minutes.

When you start talking exhausts then the cost of removing and going back to stock is starting to be closer to the price you may get from selling the second-hand parts. Factor in getting between 30-50% of the original purchase price second-hand and you'll quickly see that the effort you go through to put the car back to stock isn't worth it (unless you think you'll have a larger market for selling a stock car).

Intercoolers can be 5-6 hours labour to fit so these are also heading into the "too hard basket". Much less hassle to leave an upgraded intercooler on the car. It's something that won't necessarily effect the running of the car.

Physical mods I would do would just be bolt on stuff if there is a benefit. Stuff like dp and intake and maybe exhaust for the noise. Keen to know what are the bang for buck and simple mods worth doing with the stock turbo.

It was hard selling my modified wrx because it had extensive mods with a custom tune and it would have been cost prohibitive to return to stock. I did eventually find a buyer who appreciated the package but it took a long time. I don't want to go down this path again when it comes time for a new car even though I don't plan to sell anytime soon. Probably not within warranty period anyway.

OK for Gen 2 Tiguan this is my proposed upgrade path:

Step 1: Stage 1

Step 2: IS38 upgrade

Step 3: Stage 2 IS38 (DP and intake)

For me stage 2 tune on the stock turbo is a bit of a waste of time. For the $ you spend on putting on a DP you're much better off spending a few more $ and bolting on an IS38 turbo. It's similar gains again to a stage 1 tune and in terms of bang for buck is essentially taking you into stage 1 Mk7 R territory.

I like the response from the is20 for driveability so prob won't change this. If I can get 200kw+ atw I would be happy enough I think. Is that achievable without a turbo swap? I assume DP and intake mods needed?

Anything else easy and worthwhile?

Yes understand wanting to keep the response of a smaller turbo for a daily driver. I am yet to see anyone get near to 200kwaw with the stock turbo. You would need to have every supporting mod done to get anywhere close to that including a good DSG tune, all turbo inlet piping and intercooler piping upgraded, upgraded intercooler, turbo muffler delete, 3" DP, intake and run it on a cool morning with race gas and a 104RON map.

Or just drop in an IS38 and a tune.
