i dont think it is your ic pump, i think it is spark cut initiated by the ecu, send me a datalog and i can confirm. we experienced the same issue when we were designing the new fuel system when our regulator saw vacuum (not enought fuel), we then redesigned the regulator to see only atmopshere and boost, no more vacuum to it

 

Why don't they automatically disable it with every tune?

 

how to send datalog?i have the cable from eurocharged but i v not software,i ll contact jerry for disable it in remote,i ll try tomorrow if he can..or monday in a business day....

 

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.

 

Yes is the same is happened to me!
