the launch on these things (when tuned) at 2200rpm makes you want to puke, it just rolls the stomach. I love it. my wife doesn't like when I do that haha

I totally understand why people buy the Dinan. It gives you warranty protection(although it's through Dinan, not BMW) and it's more on the conservative side.
The JB4 is more aggressive and give you more user friendly stuff. But no warranty, and for most people that mod a lot, that's better.
I'm 95% happy with my X1. Second and third gear are plenty powerful. The top of third gear at WOT actually makes you a bit uneasy that you're going that fast. A little bit like a roller coaster. I just want that in First, and I think A tune will give me that.
I'm just scared of the JB4. I don't want to mod my x1 a lot. Maybe I'll find used msport suspension and through those on, and maybe some visual things, but otherwise, I'm good.
Too bad the Jb4 doesn't have a more conservative tune option, for those of us who maybe only want 40 more hp, and 50-60ft/lbs more, instead of 60 and `100ft\lbs.
I'm a bit scared to push the car to the ragged hairy edge. Just want a little more.
