One of our customers just got his Porsche 991 Carrera S performance upgraded with a ECU Flash at Porsche of Hilton Head. The 991 Carrera S 3.8L comes stock with 400 horsepower. Tuning the car can enhance the drivability, horsepower, and torque rivaling GT3 power. The new 991 Carrera features a SDI9 ECU which can be tuned via the OBDII port with our DimSport handheld flashing tool. The process of reading and writing is simple as seen here. Its always important to use a battery tender as pictured when writing a big file that the SDI9 requires.

Once complete, technician Patrick said, “the car drove fantastic!” Coming from a guy who drives and works on these daily, we can definitely respect his review.

 

Do you have before and after dyno runs?

 

Not for the S, this one was done at a dealership and not dyno'd. Here is a 991 non-S dyno though.

 

Last day of the month, who wants a deal?!

 

I'd like to know S dyno results. Especially after the "rivaling the GT3" part.

 

I'd like to see those dyno results as well

 

Have you tuned an X51 991?

 

Me too. Can you please post some S dyno results? If it "rivals a GT3" I am interested.

 

How can an ECU tune take the basic 991S engine into GT3 territory?

Surely this is utter nonsense???

It's a different in its mechanicals...

 

Just to be clear the 991 GT3 makes 475hp vs the 991s at 400hp, and you are saying an ECU tune will take the base car to the 475hp region????

 

It's the rival that is less powerful but comes with a gearstick, convertible top and back seats.

 

I want an explanation. If it was just overzealous prose, I accept that.

 

We are working on getting a local 991 S in our shop to before/after dyno. We have only had a local 991 non-S. If any of you are in AZ and willing to let us have your car for a few hours shoot me a PM and we can get something worked out!

 

and btw, here is what we dyno'd a 991 gt3 at (before/after flash) for comparison

 

How about track times before and after
