Hello everyone.
A couple of months ago I did a single turbo swap and manual swap on my 335. For the low pressure setup, I did a PFS double shot bucketed fuel pump. I did the DIY series kit and supplied a 525 for my secondary and a 450 from ECS tuning as my primary. I wired these connections on my own and they support a strong 80psi at idle and regular driving. as I start to creep into boost however, the pressure slowly drops and crashes at about 20 psi before throwing 29DC. I pulled the pump out and inspected it and rewired my connections with stronger butt connectors but the car acts the same. Starting to think I just need to get a new LPFP or its an EKPM issue. The car had no issues prior to the swap and was completely stock up until the swap. See the attached log. Car is a speedtech top mount 6466 and my wastegate spring rate is 12lbs.
