[84Reasons]

I have an n53 325i e93. I have installed the 3 stage manifold on this and had it remapped by evolve to hopefully gain 270 ish bhp at the flywheel. Had this on the Dyno recently and it seems whatever evolve have done equates to nothing as I have produced stock power. Nothing is wrong with the car and it runs fine and they seem at a loss as well as to why.

I want to still pursue getting the power out of the car if possible and have spoken to bimmerprofs to try and obtain some kind of direction - attached is the response. Does anyone know anyone around the Surrey area or potentially further that knows how to basically flash a 330 map onto my car? Tuners don't seem to be the right direction anymore. Any help is appreciated.
