I’ve been looking into performance upgrades for my BMW, and the BM3 Flex Fuel Kit caught my eye. I’ve read a bit about it, but I’m hoping to gather more experiences and insights from those who have already installed it.

What I’m Curious About:

  • Installation Process: How straightforward is the installation? Are there any specific tools required? A step-by-step guide would be super helpful if anyone has one!
  • Compatibility: Is this kit compatible with all BMW models? I’m especially interested in how it performs on the newer models.
  • Performance Improvements: For those of you who have made the switch, have you noticed a significant improvement in engine performance and fuel efficiency? Any real-world numbers to share?
  • Tuning Options: Does using this kit require specific tuning, or will the standard settings work? I’m trying to avoid any issues during the tuning phase.

Additional Thoughts:

I’m also curious about how it performs with different fuel blends. If anyone has any advice or tips, or if you could share your experiences, I’d really appreciate it! Looking forward to hearing your thoughts and questions on this upgrade!
