- 2020 Roush RS3 Kona Blue

I sold my 2016 PP and bought a 2020 Roush RS3 automatic. I took my 16 to the track a couple of times and never really had an issue with it launching, so long as the nannies were turned off. I took the Roush to the track once before it got too cool. I turned the nannies off on the Roush and after launch it immediately bogs down for a second and then just takes off. I did three runs, trying different things. The first time I just let the auto do it's thing. Second time, it was in sport and I shifted. Third, I think I tried Sport in 2nd off the line and then shifted into normal. All three times I had the same bog off the line. I'm not sure if it's traction control/advanced trac or something in the stock Roush tune. I've heard they dump fuel to save the cats. I know there's a dyno fuse that can be pulled; do I need to do that to completely kill the nannies? Anyone have a similar experience that can shed light on my problem? Is it the stock tune? Thanks, as always.
