Buddy if you had called Nate and paid by credit card when you first posted you would have it installed by now
took 7 days from order to delivery and that's because it was over December/newyear. Probably would have been 3 days!!
I havE had no CEL but I have had a flash tune, which from a power gain persepective, I think you should do anyway.
BMW is offering a Performance software map! I think it will be a conservative map but still it shows you that these cars are so detuned from the factory to keep them within safe perameters for longevity.
I love my Evolution System, puts the M3 into a different category, there is soo much more midrange, and the sound has no drone, so is like a factory performance car. I think the M3 GTS video best pinpoints the sound, since it has 200 Cel HFCs and is titanium to.
Do's: wipe the system down with a soft cloth before starting the car to remove grease and fingerprints from install.
