Good morning guys,
I’ve had my E46 M3 for nearly 8 years but just got around to finally wanting to mod it for more power. Specifically catless headers since the car is mostly track-use and weekend driven these days. I was reading up on time options and originally was going to go with TTFS, but for the basic options I need, it seemed like a no-brainer to go with the B-spec tune. I was reading up on the tune options and I may have missed it, but do you have additional information on each option? Particularly the redline raise, EGT disable, and sport button enhancement. I’m not ready to install the tune yet but I’d like to buy it before the price goes up.
Thanks
Zach
