Getting ready to pull the trigger on an SL and was looking for some input. Has anyone completed an ecu tune and, if so, did it give a noticeable increase in straightline performance? Are there any reasons not to do an ecu tune?

Also, given similar use, how much longer would you expect the CCB rotors to last than the steel rotors?

Thanks for your input.

 

Another question - if you tuned your Lambo and like the results, who did it?
