Hey everyone,

Just tuned my 13 ST3 last night and ran a couple data logs today. Haven't messed with any logging parameters, so I'm sorry if it's not correct. Never used this thing before and still learning the tricks. I am using the Cobb AP3 with the OTS stage 1, 93 octane, latest version (v320). I know a fair amount about engines, but some of this data is way over my head. Could someone take a quick look and verify that nothing seems out of whack? I am running this as my daily driver and would like to have some peace of mind.

Side note, holy hell, I couldn't believe how much that tune woke the car up. Nice job, Cobb! :big smile:

Thanks in advance for the help!
