Question - my R-Design came from the dealer with the Polestar tune installed (empty box for the tune was in the glove box). I'm wanting to put the TDI-Tune on the car and am not sure of the process. I've read conflicting reports - can it be installed on-top of the Polestar (stacked), do they occupy the same sensors (fuel/air, essentially) or do I need to have the Polestar tune removed first? If Polestar tune is required to be removed, can only a dealer do it? The TDI-Tune can be self installed easily, really two sensors only impacted, but I don't know the ramifications with the Polestar currently installed. I do know even with the Polestar tune, it's slow AF. I'm getting beat by SQ5s, Mayan non-turbos and even RDX when trying to get on the freeway. I can't be having that crap.

Adds 60+ hp, and 20% fuel economy?

Somehow I have my doubts.

I think those claims are definitely fabricated. I believe it does add some thing but it’s mapping so it’s not gonna add much my question stems can I put it on top of the pole star tuner? Do I have to have a dealer take the pole start tune out, or is it even worth it?

The TDI box is a piggyback ECU. You’re going to have to clarify with them exactly what kind it is. Some of them modify the signals going into your ECU to trick it into sending outputs that result in more power. Some of them modify the outputs of your ECU instead. Either way, the tune is messing with the signals from your ECU and if it’s not getting what it is expecting at a particular power level results might be.. unpredictable. As far as I can tell it isn’t a true standalone tuner ECU that replaces the stock ECU completely.

So the safest thing to do would be to remove the PS tune. But you have to realize that there is more to the PS tune than just an engine remap. It modifies the transmission as well, and possibly the stability control system. So you’re sacrificing that unless the TDI people either custom map to take into account the underlying PS tune or can certify that it doesn’t matter.

Makes sense. Thank you for the input. It sounds like I should shop for a more stable alternative that works with the polestar tune to try and get the vehicle closer to a sub 5 second 0-60. That’s the ultimate goal. I dont want anything hacky and I don’t want to lose the transmission benefits associated with the polestar tune. Thanks again!

The best answer is - buy a T8.

P* tune optimizes midrange HP, but does little to nothing on the top end. You can run a Racechip or TDI with P* so long as the piggyback has stages. For example, going past stage 3 on Racechip with P* will definitely throw codes and you'll actually slow down from retarded timing. Realistically, you'll may add 20 - 30 HP on the top end at stage 2 or 3.

Volvo cars are limited with engine tuning options, very few tuning companies do anything for Volvo, unlike Audi, BMW, Mercedes

One of the best for the VW group is the APRWith the 2.0L engine, the power gain is 50HP-100HP

and you can get over 150HP on a 3.0l engine

I have the APR tune on my 2017 Audi S8, which is my daily driver. That’s all I added to get incredible performance out of an already strong 4000 lb car. But starting with a twin turbo 4.0 V8 and starting with a single charged 2.0L 4 definitely is different.

Really just want my wife’s grocery getter to have a little more red light to red light pull. Seems to have decent pull 4000-5500 RPMs, but lags a bit on the bottom and really thins out on the top.

Thanks for the input.

You have one of the best large cars in the world, a combination of luxury and sport
My friend had a 2009 S8 with a V10 engine.
It was a modified V10 engine shared with the Lamborghini Gallardo, with tuning it had 520HP, that was the top at the time

It cost to play... I would avoid it unless you can afford to pay. We are starting to see some long term reliability issues... Just saying.
Thanks, AF. Can you be a little more specific - "who" is seeing reliability issues and can you point me to any data or reference material so I can steer clear of known potential problems? Any help is appreciated. I'm hell bent on shaving 1/2 sec off 0-60, with a budget in mind. The Polestar tune itself offers a noticeable improvement over stock, but it isn't quite where I want it to be.

Thanks again!

Hi - I can't point to anything specific; just my experience. My old BMW E90 was tuned - and it was great for 5 months. One day I floored it, getting on the freeway and the dash lit up. I ended up paying over $5000K in repairs before trading it in for my F30... I guess I didn't learn much because I did the same thing, and a couple of months later I needed a HP fuel pump (maybe unrelated), but at this point it wasn't worth it. That said, I have a few friends that have had zero issues.

I have Polestar on both my S90T5 (FWD) and XC90T6. On the S90 it is a waste of time in my opinion, however, I really enjoy it on the T6 especially from a dead stop.

Re the reliability issue - Nothing specific here either; in recent months I have paid a lot for repairs, small items but they add up at the dealership.

Makes sense. Thanks for the response. I’m inclined to just leave it alone and recognize it for what it is. It’s still a cool little SUV.

I can't comment on how the TDI box works with a SPA car. But I have it stacked on top of Polestar on my P3 and it works great. There are three sensors it plugs into: MAP, cam position, and boost pressure. The way it works is it basically, depending on which map you select, it sends a false signal to the ECU saying the car isn't making any boost, which then causes the ECU to turn up the boost pressure and therefore adding HP. From my butt dyno, the HP and TQ claims are pretty damn close to advertised. I play pretty hard with my S60 and the TDI box has made a SIGNIFICANT difference when you put it in Map 7.

Thank you. So stacking with the polestar optimization tune from the dealer is doable knowing that higher maps may cause problems.

I know when I still had my 2018 XC90 T6 with Polestar I also wanted more power... talked with Heico to see if their engine tuning module could be used on a Polestar tuned T6 engine and they said yes... and it would be additional power to the Polestar. Heico has a pretty good reputation with Volvo, they have partnered with Volvo for many years.

Never did the install though as it was pretty intensive... now have T8 ER so power is not much of an issue anymore. 😎

The big problem is that Volvo T6 is optimized for the maximum power on this engine.
The limitation is simply because it is a 2.0 liter engine, there are not many possibilities for better tuning.
You can get max 20-30HP and that's it, is it worth paying 2500$ for it, I don't think s
