I got this kit installed on my 135i. Let me say that difficulty rating out of 5 this was about a 2.5. More tedious work than anything and installing the piping and clamps from the passanger side was a bitch because of the tight space in combination with my big ass hands.
Trimming is required, but I think you should just cut the whole front plastic piece anyways.
My ADD ass forgot to dyno the car before the install so I dont have exact numbers, more like seat of pants numbers. But anyways the initiall drive was a bit jumpy with the surge of power really kicking in at 2200 rpm. As I just drove it 500 miles things have really settled in and it now has that smooth power delivery with a bigger punch.
My other mods are JB+ and DCI's. I wish I had a data logging cable, but I'll eventually get one.
Thanks going out to brian@Echelon autosports for the great deal and fast service. It was awesome dealing with him and will be looking to buy from him for future mods. Also to my buddies Jesse and Tommy for help with the install.
