Thank God this has finally turned into a mature type of technical debate

Firstly, I was merely giving advice regarding tuning boxes. I did state that yes they do their job, they do release more bhp but in a very very crude way.
It is up to you if you want to buy one and try it. Do I advise them? No I defintaley do not and think that 300dollars could be better spent on other performance mods.


Moving on, I am likely going to get slated once again but if you don't appreciate my advice PLEASE don't read it or don't leave silly comments quoting my posts. It is very dis respectable.

So I read few pages back that somebody mentioned a certain company that offers a warranty.
This is a played out sales gimmick I often see over here on this side of the world.
Example: Your turbo blows after 6 months.
A remap is detectable there is no question about it. Even though no components are added, if BMW decide to run a live reading from the OBD they can compare the logs with a standard original file and note some differences. What happens next?
BMW tell you your ECU settings have been altered and your warranty is void. Next thing to do is call your "tuner" and explain to him what happened. Now here is where the tuner has you where he wants! He is asking you to prove that the malfunction of the turbo is caused by his remap. You can travel all over the world to all of the various engineers and nobody can prove that a remap caused the turbo to blow. Yes they can guess but not prove and proof is what is needed. BMW cannot give you a statement to say that the turbo failure is a direct cause of the remap by that tuning company BUT they can void your warranty so they can basically brush their hands of the problem.
