Does my car have a chip and decat

and the ecu, no way of checking except for dyno?

Data logging on a Vbox will also show true colors! or go race a stock 335i.. I can do 100% accurate KW readings with my Vbox if we have your car's scaled weight.. Not tara weight on your license disc as they are far off!

A race will be the answer i suppose!

our 335i exhaust note had abit more grnut then the stock 135i note mainly because the 135i has a more restrictive exaust,the coupe also has better aerodynamics than the 135i
