I installed the sct sf3 on my ecoboost and put it into performance mode. I raced a 2013 v6 mustang in 4high with traction control off and locked the differential. While spooling up my turbo to 2200 rpms my rear made a huge popping noise and i chose to ingnore it and launched and won the race til 90. After the race my trcuk started to make a ticking noise then i went back into two wheeldrive. while going back the trunk started to jump around and shifted from 4th and what seeemed to be first and locked up my tires and felt like i was rear ended. So i pulled over reprogrammed it back to stock. The truck still continued to act up and even worse i could not shift into manual and the truck said it was in 4th gear and would not shift until i took my foot of the accelerator then it downshifted very harshly again till it felt like i was rear ended. Please help!!
