Very cool. My dealership has been pretty cool when it comes to mods (they resell dinan parts). Basically, if the car doesn't break because of the mod, then they don't care. However, it has been noted on my account that I track and modify my cars. So a day could be coming where they bring the hammer down. I hope it never happens as that would be the day BMW and I break up
How reliable is the car at this level of tuning? Same reliability at the track?
Can you tune for 93 octane? (east coast, best coast!)
Can I easily switch from Stage 1 to Stage 2, like on the JB4, or do I have to send the ECU back in and pay extra $$?
