Looking to pull the trigger on one of the two for my stock 991.2 CS (PDK, if that matters at all). Car is used for commuting (roughly 120 miles a week), weekend errand and joy riding, and 2-3 track events a year.

Did my first track event last summer at Watkins Glen, a month after purchasing car. Previously tracked my E92 M3, with Ohlin RT coil overs, ECU and DCT software and high flow cats. I was blown away at how much better the 911 was.


Anyway, I’m really torn what to do first. Part of me says, ‘F it, just do both!’

 

Go with you gut, LOL! Do both!

The tune really wakes the car up. The DSC settles the car down. For your described use case you will eventually want\get both so save the time commit now!

 

Do both but if you had to pick I would do the DSC first. It will make the commute even more enjoyable especially if road conditions are questionable. You won’t realize how bad the stock controller is until you pop this in. It also takes 10 mins to install. Literally the lowest hanging fruit.

 

Buy whichever you find used in the marketplace first 😊 both come around every few weeks and you can save $500’ish on either, and the money saved you can put towards entry fees/tires/brakes for track days 😊

For tune, my vote is for Softronic, he has a lot of experience with track cars and his tunes are widely used on a lot of race cars. The hand held tuner for those is tied to the ECU they’re first installed on, so buying used you’d need to find one that was bought but never installed.

 

If you have to initially choose one at first DEF DSC. For 99% of carrera buyers the stock power is more than enough, but you can never have too predictable of handling.

 

Absolutely going with Softronic based on everyone’s reviews and Scott’s experience.

 

Good move. Go with the tune first.

 

How come? I should have clarified that I’ll go Softronic when the time comes.

 

First, You already know how great the 911 handles out of the box and that the DSC will improve on that. But there's no way I expect nor can even imagine a change as breathtaking as adding an additional ~100hp the way the tune did. To me, the tune was something I wish I did from the very beginning. I didn't realize what I was missing until after I installed it. Sure, I may say the same thing after installing the DSC but I really don't expect to be as blown away as I was by the tune.

 

I completely agree. Having done both, the tune is a game changer. I did the tune almost last after cats, headers, filter and other bits. I found the stock car too mellow for my liking. While the DSC also transformed the car, if I had do one first, I'd go with the tune. But as others have suggested, do both at once. Just do it

 

I bought my 911T tuned (FVD Brombacher) and added DSC later (got it used from an RLer). I have driven a friends 911T without a tune. I would definitely get a tune first. Life is short and you will be amazed at the acceleration with a tune. 991.2 is already a quick car, but the first time you bury the right pedal after a tune, you'll never forget the feeling.
The DSC is a very nice upgrade although for me, the track is where it really shines. I have noticed a difference on the street in normal mode, but I personally wouldn't call it transformational. The tune for me is transformational...

 

Interesting. Have seen a few other post the same opinion.

 

I have both. Get the tune first. The DSC, after having it installed for over a year, I can confidently say you’re better off with static coilovers or Bilstein B16’s if you want to retain the stock PASM controller and have a better handling package.

The DSC does everything that people says it does -
smooths out the ride, improves handling/rigidity as you increase the G-forces. It is a significant improvement over stock, but personally, it’s not a replacement for a proper coilover setup. The cost forces you cross-shop actual coils… I’ll likely be selling my DSC for a set of B16 Damptronics for more adjustability (or Ohlins RT’s and delete PASM).

As for a tune, you will be blown away by the difference - it’s far from subtle.

 

Like Alexz say get the tune first and save for coilovers later

This guy with a C4S E85tune only!! absolutely get the tune first

 

I liken the DSC to a conductor. The conductor can be world class. Sit him in front of the grade 5 band, and he can help a little. Stand him in front of the philharmonic orchestra and watch him create music. My point is, the DSC grows with the car. Put it on a stock car and there are small improvements. Its not suddenly cornering like a car with coilovers and a decent spring rate. I did the DSC really early. I found sport pasm was unusable on the street. It would skip. You needed the smoothest of track for sport. Enter DSC and you drove around all the time in stiff mode. It was perfect, everywhere.

Now I have full tractive coilovers and I have constantly gone stiffer and stiffer with the spring rates. I am now at 120 Fr and 170 Rear. Manthey Racing spec, and the DSC is magically making the ride compliant on the street. I use normal mode on the street and sport mode on the track. But look how stiff I could go before even needing the normal mode. Why is that cool? Because sane individuals can have epic handling on the street with compliance. You are not constantly thinking should I make it stiffer for these quicker corners or softer for these bumps. DSC controls it all with ease.

That being said, you can never have enough power. Face it man, there is no choice. Like the little girl says, Why not do both. You know you have to. Suck it up.
