Porsche 991 Carrera Power Gains

This is awesome!

 

Nice, can you post the real dyno chart?

 

The graphs posted here are all directly from our Dyno Database. Is there a specific dyno chart you're hoping to see?

Excellent news Marshall. Really glad to see the Cobb AP on the Boxster and Carrera as well.

The graph gains look really nice. What is the secret ? Do you really get those gains just with software ? It´s very similar, even better than factory powerkit.

Is it safe for the engine ?

 

This is a good question Marshall.

 

Carrera 3.4 93 octane tune seems like a waste over the 91 octane. 3 hp and 2 lb-ft gain. As most posters here have indicated, the gains seem healthy. Almost too good to be true.
Cobb, what parameters is this tune changing to give these types of gains? I would love to see this verified by an independent user on an independent dyno. Does anyone have this yet?

 

i am thinking of getting the Cobb Tune for my 991S and had a few questions.

1). Will I feel a big difference in acceleration?

2). Is it worth the $$

 

I have had the tune about 5 days. What I notice most is how much more responsive the car is and how smooth the delivery of power is the car feels quicker but I have not run any 0-60 or other tests. I am happy with the overall improvement of the power delivery. Cobb has a 30 day return guarantee so the only real investment is time.

 

I appreciate the information. It sounds like you see a noticeable difference. Is that difference more in the low range or through out? Lastly, was it pretty easy to install?

 

I do Like it and do feel the car is more responsive in the lower range. But for me I really feel the whole power band is smoother and more responsive.

Extremely easy to install. The guys at Cobb, particularly Jared, are great and if needed will walk you through the install. Once started it takes minutes for the install. You need and Cobb recommends using a battery charger during the install. Again no big deal. You can leave the AP connected after the install and use the gauges and diagnostics or just remove it. All updates are free of charge.

I'll keep updating as I continue to drive more.

 

Hey Marshall!

I have done 2 and the guys both love it! One was a 50th anniversary w/o X51 and he feel he has meet or beat that level with the Cobb tune and exhaust/intake!

Great stuff!

hiya OP -

friend bought one of these, P/N AP3-POR-007, for his 2012.5 991 Carrera S. he tried to flash it tonight and is telling me that it backed up his stock tune but said it's not compatible with his car and thus won't flash the Cobb tune.

any idea what's going on?
