91 Octane

I was switching some exhaust parts I had from my other E90 I have ( I didn't think it would effect the tune much I just wanted to make it a bit quieter). But after the install under WOT the car freaks out and cuts out bad. I will say the Pure 600s do feel like they flow better but now I can't drive my car till I get this sorted. My apologies. First log is me staying in it 3-4th gear, second is me letting off after the cut-off.

Manual mode 2000 to 6700 ran out of room.

Feels good got ethanol sensor working now

Top end felt a little better but the service engine light still came on but it went away after 3-4min.
