After my tune in St Louis during the GTG, I was getting onto the freeway, accelerating hard but not using the magic button, when all of a sudden the engine shut down completely, for just a moment, felt like I'd hit a brick wall. I went back to the tune location and told Jerry about it. They said they'd had that problem with one od their highly modded cars but hadn't seen this problem on an SRT6 with only the mods I had. They "disabled" the tranny torque limiter and the problem was gone.
