Hello, I have a 184hp 330d which used to be a demo car for BMW and in standard form was the quickest I had been in so I assume it had been remapped at sometime.
Anyway, this is what I have done modification wise to this car and I'm extremely pleased with the results.
Full decat exhaust from Blue Flame (excellent quality) including link pipe, EGR removed, (Allard) and a K&N filter.
Totally reliable, 45mpg and goes and sounds considerably better than when I started. A torque monster.
