Performance improvements through software upgrades

Hi, I am thinking of improving the performance of my 981 Boxster S and wondered if anyone has any experience of having a software upgrade done (on any naturally aspirated modern 6 cylinder Porsche)? In particular I am thinking of DMS and Superchips (and any others you may have tried).
Thanks,  Steve

I can't help with your query, but if you proceed don't forget to inform your insurance company.

No direct experience, but when I've looked at the possibility for other non-turbo cars I've had (Jag, Alfa), software alone doesn't seem to produce much gain.

Hi Steve,
I've had experience of DMS recently (December time),  waters muddied a little as I had a new air filter (K&R) and cat back exhaust upgrade (via Carnewal) installed a few days before visiting DMS. All I would say it that the work has made a material difference to performance as per "The Butt Dyno" (I was only expecting circa 6-8 extra HP from the 1st 2 mods alone)....happy to share thoughts , msg me directly
Cheers

Try MRC tuning in Banbury. See http://www.mrctuning.com/index.php/remapping/
 
They are the go to place for Audi RS models and list Porsche as on one the other brands of cars they work on. They remapped my RS4 from 420bhp to 440bhp, but don't be fooled by the meagre gains as the difference was night and day. For example they remove the torque limiter in the first 3 gears, allow sport to be engaged all the time instead of only when exceeding 3,000rpm, ported manifold, gutted pre-cats etc. I really don't know what they can do for your car, but I do know that what they do, they do very well.
 
Cheers,
Bryan

Hi Craig,
Not sure how to "message you directly" but interested to know which model you have, what DMS did, how long it took and what it cost? How has the improvement manifested itself?
 
Hi Briggy,
Thanks for the lead - I have emailed MRC.
 
Regards, Steve

FVD are well worth checking out . They are one of the best with proven and safe results .
The 981 S is a detuned motor and responds very well for moderate cost . On my list 
if i keep this car .

I would avoid the VAG boys tuning shops on Porsche tuning.
 
but really a 981 will get you 10bhp as most so it's not worth the risk
you need to delete some cats and increase air flow then you can  get 380BHP from the 981.
 
only people really tuning the 981 is COBB and Jens, leave everything else well alone.

Radio ? NONE.
Cup Holder? NONE
Air Condidioning? DITTO
A pure roadster. Reduced to the essentials
Still the fastest...

Don't forget if you have a Porsche Warranty any Mods  may  invalidate your warranty.

Hi Cliff, it is because my Porsche Warranty has run out (and they would not renew - but that is another story!) that I feel free to start tinkering. Given your role and obvious extensive Porsche experience, have you found them to be reliable even when tuned?

Sorry Steve we have never tuned a Boxster because of the warranty I think at best I once changed the air filter to a K&N.
I think from my understanding on Normal Aspirated engines its small gains unless you start spending big money.
Obviously a different story on Turbo models I suspect.
Probably better off upgrading brakes and suspension if that's your bag especially if tracking or even going on a driving course.
Most Porsches I have owned are more than capable on todays roads or the occasional light track day.
Might be worth a call to our Technical Boxster advisor Steve Winter at Jaz Porsche in St Albans.
Cheers.

I work in a engine test lab on dynos for ford  and jaguar, n/a engines can be tuned but as said above you will only get small gains,turbo engines you will get good gains just by increasing boost and fuel.and timing,  if you look at a 981 boxster engine it is less powerful as a 981 cayman engine I bet the base engine is the same it is all done in the mapping ,same as some ford vvt engines ,a few years ago we had a 1.6 vvt sigma engine which could have 115 ps,125 ps or 136ps base engines were all same,just maps were different.

FVD Brombacher's tune safely pumps the 981 Boxster S from 315 hp to 352 hp/291 tq. I'm not normally an advocate for tunes since most aren't the product of actual automotive software engineers, but Germany's FVD Brombacher's software engineers were actually trained and worked for Bosch and Siemans in Germany and have extensive factory expertise in writing software code for Porsche. They also don't remove ANY of the OEM software safety features. Win-Win. 
 
Cobb , as mentioned above , are at least as good and offer the same gains for 981 S .

Thinking about doing the same myself.
 
At the moment, I'm looking at 3 options:
 
DMS - seem to have had the best reviews in regards to just a tune
Celtic - good history of tuning but figures quoted are less than DMS but are half the price
Cobb - most expensive
If I can get a Cobb Accessport with PDK flashing for a decent price, I think I will go for that. Tempted to give DMS a go though.

On a normally aspirated petrol motor you're likely to see an increase of 3-5% on the headline BHP figure. However a decent remap can be tailored to iron out a lot of the legislative emissions related compromises in the software improving drivability massively in some cases and scoring a huge gain on the seat of the pants dyno. If you want to speak to someone reputable about this, I can recommend Iggy at Zensport. He's on 01376335947.
