Thinking about a Cobb AP tune, need data
COVID travel restriction boredom is getting the better of me and I am thinking of doing a Cobb AP tune.
I have searched Cobb's site, and pretty much the entire internet, for data but can not find anything on what gains to expect with a 100% stock 996TT running an Accessport V1 tune. Contacted Cobb and they don't even know.
Has anyone here run a Cobb AP V1 tune on a 100% stock 966TT and can give me some data on potential gains?

i read in the porsche material years ago they used 600 cell cats and felix's web site confirmed that. i couldn't locate the white paper just now, but one can't believe everything they read, right?
but i still believe that they are 600 psi and it is widely reported that oem system cats are 600 to 800 psi.
the quote from felix's site
The Factory setup produces the most lackluster sound, mainly due to a series of chambers, 600 cell catalysts, and the most prominent flaw being the lack of balance between opposing banks. Seriously, i would recommend when considering any aftermarket exhaust for a Porsche turbo, never buy an exhaust without some kind of gas balance between left and right banks. replacing the stock cats for a choice of 100cpsi, 200cpsi, or de-cat increases the sound respectively. Replacing the chambered transverse rear silencer with freeflow harmonically tuned silencers enriches the sound, and the addition of our trademark 1D CLR laminar flow X pipe raises the exhaust pitch beyond the region in which bass noise is able to penetrate the cabin, while under hard throttle and high revs, a rich and raucous vocal ensues. This design was pioneered and innovated by Kline, however several copycat designs have started to appear."
but you make exhaust systems, so i'll defer.
but thanks for your input!

Here is a cat of a 996 Turbo factory exhaust, about 17 cells vertically and 18 cells horizontally in a 1 inch square area.
17 cells x 18 cells = 306 cells

Hey Carlo. I'm pretty sure we are local... if you want, i can unmarry my AP from my car and you can load a tune into your car and see if you like it... i'm pretty sure that with a non x-50 on a stock car, it should bump the boost from .6/.7 bar to about .9 bar... a stage 1 is usually air filter...

if you feel like a science experiment, we could take your car to the dyno and do a before and after stage 1

Umw has the datalogger yes, it has no lcd screen and im not sure if you can connect it from obd2 to laptop to see real time logging.
ap v3 has a multitude of functions including gauges like afr but isnt as accurate as say a weldin secondary bung sensor. It uses obd2 and its actually really really useful, the group of friends i hang with have ap on a focus/gti/997tt they all use it for afr etc gauges.
From what i know about the ots tunes with cobb on the cars they are married to is its a generic tune that its not really comparable to say a custom tune.
Ots tune on focus st adds like 40hp from stock with no breathing. The stage 2 tune adds another 40 but you need intake exhaust and bov.
Iirc the car is now custom dyno tuned and runs 300/280.
So... Its probably along the same lines for our cars.

Contact Sambo at By design Auto. He has good pricing on the Cobb AP, he does an great job on custom tunes and will take care of you. I think in a previous post he may have stated like Plus 50-60 HP from just a Cobb (or somebody eases tune) on a basically stock car. Consensus is that you will definitely feel it. I like the Cobb because you can use it like a little real time engine monitor after loading the tune.

It will be faster, it's great bang for the buck, and you will not regret it.
COBB AP is great because it has a nice user interface and other functions. The flash loader that UMW, Markski, and other less popular tuners sell you are much more rudimentary and are really only used for loading tunes, but they'll charge you pretty close to the same as a COBB AP v3. At least with the COBB you can check codes and have some extra data points displayed if you mount it. At the end of the day, you still need Durametric to have a complete package along with a flash loading tool.
