Thinking about getting JB4 N54 Chip on my 135i reviews?
Hey guys my 135i is completely stock and I really wanna add performance to it and add speed and horsepower. I just wanted to see if it\'s caused problems to people\'s 135i\'s and how much horsepower it\'s added. Any reviews would be helpful. Thanks!

I installed the BMW Performance Power Kit - Stage 1.
BMW claims to add 20HP and 17 lb-ft, but we all know that's underrated. It has not caused me any problems. I have posted some before numbers. Will be updating with after numbers soon. |
