[niqui]

Hi, i have a bone stock e92 m3, and feel as though i am lacking a bit of low down torque, and kinda desire a bit more pull. I was thinking of doing the ecu flash from AA, but was wondering whether it is worth it, espeicially on a bone stock car. This is likely to be my only mod, so will I get a lot out of it, and is it worth it, and voiding the warranty? Anybody have a car that is completely stock with just the ECU flash because everyone i know who has the AA ECU has many other mods, so its hard to judge... Will i feel it in a daily driving or only hard driving/track?
thanks
