Yeah, mine used to taper, or not rise as fast. But now after 15 psi, it very slowly drops. Given my boost pressure test to 20 psi, I’m probably not leaking much. There really isn’t anything that could collapse. I’m already at 80 duty cycle and I over purchased for all my fuel components. 485 pump, S1.SE with the new rails, and 1050x that was supposed to be good for well over 600 WHP. Should have gone for 1300s, but no one indicated I’d need that. In fact I have the same components as the Topgunz ACE kit car. I’m on pump and have already hit 80%. It breathes very easily now with a 4” intake I guess.
