Ok so I recently bought a Cobb tuner for my '10 335xi (I know I know COBB in 2025 it was super cheap off marketplace lol). Anyways I flashed stage 1 at first and the car was perfectly happy with it, hit boost levels (10.8 psi) perfectly fine and was healthy doing pulls all day. Last night I flashed Stage 1+(14.5 psi), just to see what it could do, and even half throttle it felt wayy different, but then I tried a full throttle pull in 2nd or 3rd (sorry I forgot), and it built boost up until ~4500-5500 RPM, where the CEL came on and the car was in what Im presuming was limp mode. I pulled over and turned the car off and flashed back to my stock tune, and there was no issue after that, the car made stock boost levels perfectly fine (~7-8 psi). After arriving home I scanned the car for any codes, and all I got was "CF61 Distributor Gear Control unit" and a "5F56 DSC" code. I cleared both of these, and they did not come back. My main concern is trying to find the main cause of this, coils, plugs injectors? I have heard some people say that hitting a bump can engage limp mode (and I did hit a bump), so could that possibly be why? The tune I had loaded was for 93 octane, and I am in Canada running 93 octane, but a friend of mine recommended that I switch to the ACN 91 maps within Cobb. Any advice would be appreciated, as this has me kinda worried. My car is fully stock, except for DCI's, and stage 1+ does not require any actual support mods, although I do have a metal charge pipe coming soon. I also only have 105,000 kms on it, and it has been VERY well maintained since brand new

Thanks in Advance
