AMS Tuned 997.2 Turbo S. (Dynos Inside)
The purpose of this thread was not to start a vendor war. Softronic is a quality tune I'm sure but nothing beats a dyno tune at your local shop if available. My problem may have been who tuned my car with the softronic software. However I will come out and say I'm extremely dissatisfied with agency power, I do not believe they are reputable or make a quality product.....still have not heard a response from my multiple emails to them.
The file that you had in the car should have generated around 541HP at the wheels in which by the dyno doesn't make any sense in relation to the TQ stock or tuned with the Switzer file. The same file had been used extensively and tested using Vbox data in DFI 997TT's with very good times. These times would not have been possible without the HP and TQ increases from a stock DFI PDK turbo. The Vbox data had been done with stock cars and later with exhaust systems. The DFI cars flow well with the stock exhaust and can show gains with other exhaust systems yet not as dramatic as the earlier turbos.
I know Mitch also as he used to work for Vivid.

I really wonder what kind of HP/tq will make on Dynojet
Not true as Proto and Switzer tunes are done via logs remotely and others .... The one that was done in Kuwait that posted Vbox data well over a year ago was a PDK 997TT.2.
He made ( His tune + X-Pipe system ) 80whp/90wtq vs stock baseline
Everything onebadgtr is posting is true. We did indeed pull his stock file back in September. I'm a little confused by your posts in here softtronic. Your posts are coming off very defensive. All onebadgtr is doing is sharing his experience and doing so honestly and accurately. He has said multiple times while he is happy with his tune he was not unhappy with his previous tune. He is however upset with the intake that came off the car and he has every right to be.
While we might be fairly new to the Porsche scene we are far from new to tuning. We have been tuning turbo charged cars ranging from 200-1600whp for over 10 years. Martin,Chris and Mitch combined have over 25 years of tuning under their belt.
Shortly you will see 997 packages released by AMS. The latest of which is a very quick spooling package that produced 830whp on our shop 997.1. We are not trying to make any enemies with the current players in the market but we also don't feel the way this thread is headed is really necessary.
Nick, we are thrilled you are happy with your car and as always we are here when you need us.

It just makes sense since every car is different, so by dyno tuning you would think one can improve vs. throwing on a generic mail order tune. Maybe not on peak hp but on areas under the curve.
I'm Pming you..I don't want to hi-jack the thread bro
When I switched tuners from EPL to Protomotive,I can agree in what you said about its more then peak numbers..The Protomotive tune was much smoother , more responsive,made a little more peak HP+TQ on less boost!..
They both tuned my car while it was on a dyno...I made a thread on it back then and some still dont understand anything but peak numbers..LOL..

The 'aftermarket' intake and tune made 499WHP and 522WTQ. (The way I brought the car in.) [/i]
Then reverting back to the stock tune and stock intake the car made 509WHP and 546WTQ!
The AMS tune and stock intake was able to achieve 539WHP and 576WTQ!
Thanks again AMS for the great service!

However, I do believe that the 997.2TT dfi engine is under rated. A bunch of tuners have confirmed so. Evoms stating they dyno tested their stock 997.2 TT and got 490 AWHP and 490 AWTQ
I spent some time on the dyno today with the new turbo. Since this is the first time dyno testing the new platform, I spent a solid 4 hours data logging AFR, intake temps, water/oil temps, boost pressure, EGT's, etc to see how all of these variables affect the power. The car is pretty consistent in terms of power delivery but is still very temperature dependent. After about 35 dyno pulls in 3rd, 4th and 5th gear, I was able to decipher the data and get the car to make very consistent repeatable power. The highest power was ~490 AWHP and ~490 AWTQ. The average power was in the 480 Range. There was very little difference in power with or without sport mode. Overall I am VERY impressed with the power and I think that Porsche has under rated this one.
For comparison, listed below are some other stock power figures from our same AWD dyno:<O

997.1 TT puts down ~438 AWHP and ~431 AWTQ to the wheels
997 GT2 puts down ~476 AWHP and ~466 AWTQ to the wheels
997.2 TT DFI puts down ~490 AWHP and ~490 AWTQ to the wheels

You have a Turbo S so I would expect bigger #'s than the ones above

Well , its not my right to write about my car in this thread , but i will share some of my exp about fine tune the car , as many of you knew that am running 997.1 with GT30s and external WGs .. Etc etc ! I got a base tune from softronic 2 years ago , after i installed new meth kit he sent me new file and asked me to log some values then send it to him , after that he send me new file with new changes ! In my opinion this way Is less costy and easy to do data loging and retune to fit the changes ! The way i can know that the tune is much powerfull is to get vbox times ! Same road , same time , some boost and test !! Dyno is not a thing to know how much power the car has ! Diffrent dynos , diffrent settings , etc etc !!! Vbox only the best way to do it !
Thanks .. !
Thanks .. !
Again we have been writing files for the better part of 10 years. We don't just tune... We manufacture parts, build engines and build complete cars. Tuning isn't just about a guy sitting behind a keyboard or loading a file. It's about understanding how an engine works and how it's going to react to the parts installed.
It's for this reason we have been so successful in the GTR, EVO and STI world. It's these same principles that we are carrying with us to the Porsche world. Honest advice, PROVEN PARTS and flat out results.
We are not asking everyone to drop what they are doing and abandon the tune they have on there car now.... Quite the contrary in fact. If you are happy with your current tuner or your decision on your future tuner then by all means please stay the course. If you are not happy or want to try something different then maybe give us a call or shoot us a pm. That's all... No More no less.
We are not saying anything negative about any tuner on this site. Our customer was just happy with his experience and wanted to share it with the site. That's all, no need to make a mountain out of molehill.
I am here to answer any questions you might have so ask away.
Eric
