let me start by saying the truck is mostly stock it has a fass 165 gph pump,3.5 pusher intake horn,pusher3” intercooler piping,s&b intake, fuel rail plug,625 studs,mm3 drd tuned and deleted. stock 68RFE. tires I’m on 33” courser all terrains

so tonight I was roll racing. i was doing a 30mph roll in second gear using the manual gear selector and I was brake boosting to about 29psi of boost. when I let off the brake and start going through second shift into 3rd at 3100 rpm then go through 3rd and shift into 4th at 3000rpm when I hit into 4th the truck died instantly. I think it’s something with the converter or just when I shifted the tires grabbed to much and made the truck turn off when the converter locked up. not sure what happened I checked the stored codes there’s nothing on there so not sure what it did when I shifted. truck runs fine drove it 50miles home no codes poped up
