Wait a minute... I heard a weird sound several times when running it hard. I thought it was something in my door cubbies rattling. Never thought it could be fuel pump. I'm only on stage 1 running 93 octane.

Sorry I didn't respond sooner. It is definitely the fuel pump. It's crazy. It does it in all modes except ECO. I have reached out to PTF a couple days ago and waiting to heard back. I asked it they have had this happen often on stock cars running stage one 93 octane. I will keep you guys posted.

I may just go HPFP

Limited response from PTF over the weekend. Sent in a few logs for them to review. Hopefully I hear something definitive tomorrow.

Update: 8/19/2019

Finally hear back from PTF. They reviewed my logs and said they looked fine. I am going to try to record the pump and send it to them tonight. Afterwards I will sadly be flashing back to stock until I can get this sorted.

Did you ever get an answer? Most times I hear people talk about upgrading the High Pressure Fuel Pump to a B58 pump or the XDI-35. Which is like $2k. But other times I read talk of replacing the Low Pressure Fuel Pump. (Is that the one that pumps between two halves of the fuel tank?)
HPFP is obviously for higher boost/ more power. Anyone have a good explanation for why the LPFP needs replacement/ upgrade?

I think I am just going to have to upgrade the damn pump. Makes no sense being that I'm only running stage one. I was going to post a video but it won't let me
