I'm still fairly new to the 981 game so sorry for the rookie question here but I recently added a Cobb Accessport + PDK tune and some filters to my GTS.
I'm now considering Soul long tube headers to really wake it up. A Cobb rep said if I go with headers I'll need to take the car to a tuner for a pro tune. So, is the accessport obsolete at that point, aside from the PDK update? Or does a 'pro tuner' utilize the accessport?
Didn't do my homework on all this ahead of time, obviously.
I don't track the car, really just want a little more grunt when I'm doing some spirited driving.
TIA

The pro tuner still need the Cobb Accessport to tune your car. Instead of the OTS map tune from Cobb, the tuner will make a custom map depending on what mods you have and the dyno results then use the access port to flash the ECU of your car.
My 981 S has sports headers and is pro tuned. Compare to the stage 2 OTS map from cobb, it made more HP and the power delivery was much better and smoother.

Yes, It is intended for cars with high flow headers. I did use it prior to getting pro tune after my headers was installed. I did feel a little bit difference from stage 1 OTS, but it felt more polished when I had it pro tuned. It ended up making 320HP to the wheel on the dyno. Stock PSE exhaust and high flow air filters, btw.

Beware COBB tuning and aftermarket catless headers. I believe COBB has disabled their protuning software from eliminating cel's due to catless headers. It seems like it would work if you purchased the headers with cats. I would speak with your protuner before making any purchases to be sure they can program it the way you want and without cel's.

Thanks for the replies. Headers will arrive tomorrow and I was planning to install this weekend. Am I okay to leave my OTS accessport 93 octane tune as is for now or is it better to just put the ECU back stock until I can get setup with a pro tune? (which I will do soon, it's on my list)j
Thanks again.
