Maybe one day. But thatíll probably be after someone else shows the improvement. So hopefully you will be on the dyno first haha

You get rid of the 2.5Ē 2 into 1 y at the back of the exhaust? That made a nice difference Iím pretty sure.

I thought Twisted fixed it for someone else by just starting a new tune from scratch. I could never figure it out, the E30 BEF had no issues. I see you are MT, but thought I'd share.
Always good to hear similar issues that may help someone else 👍🏽

335i exhaust isn't nearly as restrictive as it keeps the 2x 2.5" all the way back. I haven't ever been on the dyno, so not sure how useful the results would be for a comparison.

Updated op on 1addicts with stock turbo dynos on PPK and E30. Also updated PS2 dyno graph so you can see the difference between my stock and PS2 results.
