Oh yes, I see you are driving on the highway in 7th gear which I don't do. I have found 7th gear to be unresponsive no matter what tune or not I have on the car. It was unresponsive when I bought the car on the way back from Dallas before I ever got a tune so I just stayed away from it. I don't think that has to do with the tune, I think it has to do with that being nothing more than a cruising gear.
Very interesting. I noticed a similar drivability issue on my Cobb Stage 2 tune as well. When I'm cruising on the highway in 7th gear at 85mph, the throttle is very difficult to modulate and the boost would oscillate back and forth between 6psi to 12psi sometimes. Put simply, if I'm feathering the throttle to get some mild acceleration, the power comes on too strong and I need to back off the throttle, but the power goes down too much if I back off 100%. We need a new update please!
We are also releasing two sets of maps with different throttle settings in the upcoming update. Factory non-linear throttle(stock throttle) and linear throttle maps. The linear throttle maps will have a 1:1 ratio for the correlation between throttle pedal and throttle plate. The Factory non-linear or stock throttle maps will remain as the car comes from the factory and as they currently are now. Since every car is a bit different and everyone's driving styles vary it is nice to have the luxury of having so many maps and the versatility of the Accessport to quickly download, update, and flash many different maps to suit your driving style.
In the mean time if anyone else is encountering this please feel free to email me and I will expedite the process to get you a map before the official release.

As always, these updates are very easy and can be done in your own home in a matter of minutes.
Thanks again everyone. Your feedback is extremely valuable to us and we take it very seriously.
If there are any questions feel free to reach out to us at anytime!

No, it's definitely a drivability issue on the Cobb tune. Since I didn't change the way I drive, I never had this problem with the stock program or the GIAC Stage 2 in 7th gear. The Cobb tune is definitely much stronger than the GIAC tune, but GIAC is smoother and better calibrated in certain places.

I noticed the turbo boost on/off switch like effect in my friend's 991 TTS when it had the off the shelf Cobb stage 2 tune. But when he was reflashed with the custom stage 2 file on John Morgan's car the jumpiness got much better he said. John Morgan's 991 TT with the Cobb stage 2 custom file did not seem very jumpy and it was much faster than the OTS Cobb stage 2.

I think in summary the answer to this question lies in which tune best suits the end user. Some users never track their cars and to be honest have never tried to launched their vehicles yet come to an online forum and salivate over the need to tune. Others participate in road race, 1 mile/ 1/2 mile events, etc,etc. and have a need to be competitive as no one likes to lose. Some are power users like WRS who love data and can orchestrate data with the Cobb AP data logging like a conductor of the Phil harmonic. Others just want a bit more torque from light to city light and will never even remove the AP from the glove box to plug the AP into the OBDII port. Moreover, there are others in between and also outside of these parameters (think Alpha 10-20 and the need for a 200 mph trap in the 1/2 mile).
In my experience, the great thing I've learned about Sam/ Cobb AP is the ability to accommodate any configuration and tailor the tune into the end users specific requirements via the AP. Im convinced with Cobb there is no close second as they are responsive and competitive today and not making promises about "tricks and products coming". I'm one of the guys who passionately believe that your client is your business and must be treated as such. I can relate to like minded attitudes of service like efficiently responding to inquires and customer needs.
Anyone who has tried can attest to Sams response times along with Cobbs unparalleled tuner access. Simply send in the data logs along with a tune request and be awed with the turnaround of a revised tune. Every vehicle and end user is different, I like alot more throttle sensitivity whereas others think its jerky or too sensitive. These are all areas mastered by Cobb in tailoring the experience to the driver given the time the end user is willing to make the experience his own. Some tuners tune for a common denominator experience with Cobb you have the ability to make the tune your own.
Regarding racing anyone can blow the tires at launch or fall asleep at the tree and lose a race. Trap speeds and overpowering to catch and pass your opponent tell a definitive story. I have invested in both mentioned tunes and for me Cobb has evolved with me and my needs like no other. Prior to purchase I've researched them all whether it be piggy back or otherwise. I'm still growing with all of the Cobb AP functionality including data logging and the ability to utilize it. With other tuners this must have functionality is not integrated as a standard feature set and you are at the mercy of the tuner to recognize the need to revise the tune to make you more competitive or tailor a tune to maximize a bolt on that you've just installed.
In the end find what best fits your needs end enjoy with zero regrets. May you live it to the fullest!

We know you love your Cobb software, and you have every right to. They make a great product, there's no denying that. But the GIAC and Cobb software have different characteristics that make them different. The OP has had both, and he prefers GIAC. Some people love GIAC, some people love Cobb....I'm not sure why you don't want to accept that LOL.
