ER Chargepipe installed - impressions
Helix Bimmersport in Philly installed my ER polished charge pipe and BMS Stage II tune yesterday - Eric is a great guy and does good work.
The charge pipe has an OEM fit and is well made. Eric said it was a little tight but otherwise was uneventful. The stock plastic one - mother of god, it's a toy, it has no business being in a 335. I wouldn't even trust that with stock boost.
I'm impressed with the BMS Stage II tune. I put it in Map 2 as I have the AR 4" downpipe (BMS says 14.5 PSI but I haven't measured), it pulls like a mofo. The power delivery is wonderfully linear - it's like stock only has a lot more power. And it holds the boosts between shifts.
Overall I am quite pleased!
