BMW 335i N54 tuned by ECU Tuning Group

After lurking on numerous forums all these years trying to get good advice on tuning my 335i, I went with ECU Tuning Group and haven't been more happier looking to drive every day.
I'm a member at n54tech.com, bimmerboost.com, and e90post.com too, so I wanted to share my experience with those looking for something better than a piggyback.
I have a baseline dyno from 034 Motorsport in Fremont, CA and will post it as soon as I get a post dyno done after full adaptation. I know everyone wants to see dyno sheets and so do I.

034 Motorsport does my OBD1 chip tuning for my 4.9L M62 E34 540i. Great shop/tuner.

I came from stage4 335i 6MT but never heard of ECU tuning group. 335 is a good car and fun to drive but had replaced 4 high pressure fuel pumps failed. how does your hold up ?

high pressure fuel pumps are common failure, so far BMW hasn't come up with a solution.
