BUTTTT with all those mods for a 12.6? We ran a 12.74 in a 4 door 335i auto with the stock 18's with just our custom DME tune. Maybe just more seat time in the car can improve it? Good luck dude!
Thank you! And yes myself personal will be practicing n trying to improve as well.
Thank you for the positive feedback.
