I know I’m new to this forum, and I have a 718 Base, but I have Cobb stage 1 and have the same codes as you. PDK and UC401. Trying to figure out what is causing it.

I got a question two for those with chrono pack
does the tune stage 1 or 2 retain the default characteristics of sports and sports plus mode?
in sports there is backfire
in sports plus no backfire but constant boost of 1psi at idle and always on boost

My friend has cobb and after a recent update the sport and sport+ burbles got mixed up. None in sport and burbling in sport +. Not sure if other folks have this experience as well. Everything else works as stock afaik.

I plan on using access port just for upload/download of custom maps, still have 600miles to go before breakin
plan on tweaking just the sport and sports+ maps for a bit more power, all custom. nothing aggressive. Dyno/road tune to make sure its a daily driver.
I am Apex Autoworks lined up in NJ

I would make these changes before scrapping the COBB.

Just curious if there is any data/logs to back this up? I have been running stage 2 as well as doing pulls and logs with John at BGB for a protune and have noticed no issues with the stock air filter and stock intercoolers (my only mod is cat bypass pipes). The intake air temps are actually really close to ambient temps (or even below depending if the wing is up or not) and it seems to have no impact on knock or timing pulls. I do agree that the air filter and intercooler cannot hurt-just not sure how necessary they are off the bat.
