For COBB a Protune, not sure of the cost, by Dzenno looks to be the pick of the litter.

Cobb and the JB4 are definitely proven and proven again and again time after time. I had a water pump go out on me, but idk if that was jb4 related.

Yeah the installation of the JB4 isnt THAT bad but I already have a messed up pin in the ECU from taking it on and off every time I take it in to the dealership.

I really like this simplicity of the installation! but it is more expensive and no on the fly switching between maps! I love going from no turbo to stage two!

took out the jb4 for the warranty work then put it back on.
One of my pins broke so I will have to get that replaced for future installing and uninstalling.
But I plan on getting another 135i or a 335i
Pain in the but. But performance is amazing with no other mod.
