Finally my 128 feels quick!
I love my 128i and it's the longest I've ever held as my 2nd car, but I've had this ongoing issue with how boring the car accelerates. In order to remedy this, I added mods in steps and finally feels great! Mods were added as follow: 3IM, Stage FP tune, 3.73 diff, Milvs. Car also has AFE magnum stage 2 intake and 135i N55 catback w/resonator delete.
Below I'll explain how each mod felt and what was lacking IMO. 3IM+Tune: This helped wake up the low to mid range and should've came from the factory this way. It was nice for a bit, but after a month I got used to it and felt kinda boring again. 3.73 diff: Because of the nature of the lower gearing, the car revved more freely, which also resulted in naturally shifting at a higher rpm. It made the car feel livelier, but didn't really feel faster if that make sense. Milvs+Tune: WOW, it all came together. The milvs added power everywhere in the rev range and really made the lower gearing worth it. Now the car really feels like its going somewhere with the quicker revs. Finally the car feels fun in all situations from just putting around town to spirited drives. Tl;dr: 3IM+MILVS+Tune+3.73 diff are the tits. Last edited by NA64LIFE; 12-10-2020 at 04:46 AM.. |

Good to know. I don't think I'll ever alter my MILVs, but I do plan the 3-stage intake and I've already done intake and exhaust. The one final thing I might try are AFE Twisted Steel headers.
I'm surprised to hear your opinion about the 3-stage intake. Looking at some dyno charts, I thought most of the power came up high in the rev range which is where I think it falls flat. Sadly my transmission doesn't shift smoothly enough for me to consider going with a 3.73 ratio. I couldn't shift fast enough to see much benefit without roasting the transmission. I'm most excited about replacing my dual-mass clutch and installing a new giubo. I can't stand the rubber band effect I feel in the drivetrain from time to time. To me, that will really liven up the driving experience.

Finally for those on a budget or aren't "wrenchers," I wanted to share my secret for making my car feel faster. It's a simple three step process. 1. Park the 1 series 2. Drive a 2003 Honda CRV Automatic for 20 minutes. 3. Drive the 1 series immediately thereafter. It will feel like an F-16 Fighting Falcon with clean profile on afterburner and sound like front row of the Philarmonic. : ) Best wishes. |

As for the headers, I'm not expecting huge gains from the AFEs, but a little would be nice. I would also hope for improved sound.

As for the AFE - I've read a bunch of reviews, they aren't super popular as most go for AA, Supersprint, or the cheaper AA knock-offs - those are all cat-less. The AFEs some people said didn't last long (the Catalyst portion)....but again, sample size is small. Good luck! |
