-What I'm looking for is quite simple:
-a well-known manufacturer who has a real product with pricing and real field-proven specs
-tuning kit with controller box plus required wiring giving me approx. 170HP/PS
-a simple installation manual, with simple installation that can be done in less than 1 hour
-a tuning result, that will give me 0-100 specs close to the 118i performance
-motor warranty would be great also
-It seems to be much more difficult that I have ever emagined...I should have bought the 118i from the very beginning....
