My apologies for continuing this barrage of unhappy comments. I was doing my best to stay away from this thread because I'd hate to be one that causes a company business.. But;

This tune/dynograph looks horrible. You get a huge punch of torque down low, and then as you go higher up into your RPMS the power falls on it's face. This will rob of you of the NA feeling where the pull is all the way to redline. A fast way to kill the 911 character.

The purple line which is the stock tune looks so much better. What a joke

This is simply not Fabspeed’s call on what information we can share. I called our tuner to see what he would be okay with us sharing and, unfortunately, he is out with a Family Emergency for the next few days at least. Hopefully if everything is okay with him and his family and we will be able to get some more information for you early next week.

We don’t have an official warranty on our tunes because we have never needed on. We have not had any issues with a tune. We stand by our products 100% and have worked with various customers who were skeptical on the results and provided the necessary concessions that made them comfortable to move forward, and all of them have been pleased with the outcome.
What type of warranty would you look for on an item like this? Are you concerned the tune would cause damage to the vehicle itself? We are not against creating an official warranty for tunes as we already do work with our customers and stand by these 100%.

Torque is much more important in the lower RPMs as the engine is gaining power, then it reaches a point where the engine is sucking in more air than the turbo/engine can do anything with, which is where the torque drops off and the horsepower takes over more. If the car has a larger turbo you would see the whole curve move the right as the threshold where that occurs would be at a higher RPM. All that being said, the tuned car still ends the run at 50 ft/lbs of TQ more than stock which is quite substantial.

Not sure what you mean by that, since the tuned car has much higher performance and reaches max power much faster. With the torque gains provided by this tune, you would take off like a rocket.
I’ll check back early next week to see if there’s some more details I can provide you guys on the tune. In the meantime, just let me know if you have any other questions.

I'm worried about taking my car to the dealer for engine, transmission, or electrical issues, and Porsche refusing to cover the repairs because it feels that the damage resulted from the aftermarket ECU tune.

There's a limit to how much torque you can shove through a drivetrain before something breaks or wears out prematurely. I doubt this tune would exceed those limits on my base Carrera since it would still make less power than a GTS, but it's certainly in Porsche's best interest to take that position and refuse to cover major repairs on a modified car.

John@Fabspeed

That is a great question. First, You should definitely talk with your dealership to understand were they stand on tuning because they are going to be the ones battling for you to get your issue covered by Porsche. Second, They have to prove that it is the tune that is causing the issue under the magnuson moss warranty act. They can not just void your warranty and say "ooo it is because of the tune so we are not fixing your radio". Lastly, As stated before we do not push our tunes to create issues, we keep our tunes fun but not to hurt the vehicle.

PM M/// he has that data for his GTS following the Cobb tune. Also Cobb did release a screen shot of AFR for one or more of their tunes on their thread.

The reality is simple, to tune a car you play with AFR and timing - and in the case of turbos wind up boost.

The other simple truth is they to gain power they have to increase boost and run leaner - its a fair question to know how lean and roughly where the knock threshold is/appears to be on these cars.

So a simple question would be - what is the AFR and boost and how far is the timing advanced at 6500RPM and where is the knock threshold relative to these three numbers. I would also want to know how much duty cycle with regard to fuel/fuel injection is up the sleeve.

The Turbo era tune threads and subsequent conversations make me wonder why the conversations are so much different than what they used to be for decades before turbo era.
surely the turbo cars didn’t invite a different customer base or members?
the conversations are increasingly awkward, passive aggressive and sometimes downright rude.
NOT saying that is what is happening in this thread but there are hints of it all over.
no one is pressuring us to buy anything. Neither are these companies in the business to make short term $1499 or less only to ruin their reputation for ever.
turbos are here to stay and I would hope that all these timers are hoping to have long term customer base.
my 2 cents

APR Tune with zero pdk issues, enjoy..
