Well that fixed that problem. With the feed pinched it holds 60psi. So I will redue the fuel pump set up an try it again tonight with out it being pinched

Ok well I fixed the fuel leak. But with the return line hooked up its causing a lot of turbulence in the fuel bucket, (like a ton of small bubbles.

Idk if that will cause an issue. I drilled the bottom of the fuel return plastic piece out like I read I had to do. Maybe I did it to big??

Also increasing the pressure at the regulator didn’t help but it only is rated 40-75psi so may still not be enough. Any thoughts?

So it holds pressure on it's own now? If so cool man.

I'm not really sure what you mean about the return line deal so I can't really say much about that

Yea holds pressure now. Best way can describe it is like putting a bubbler in a live well for bait fish. Lol sorry not the best at describing it.

Sounds like air in the system but I can't picture how air would be ingested into a pressurized system, if I had vacuum on it anywhere it would pull air in from atmosphere if there were a leak.

So I don't know man, I've never watched a fuel return into a bucket so it may be okay....?

Ok so after pulling my tune, I went to Main VE table. Noticed that he still has me at a 1bar map table as it only goes to 105 Kpa. Also has mass air flow set to 100hz is that correct?

Got it figured out thanks to ATOMIC. Comes to find out besides all the small problems, I found that the guy who installed my tune pretty much just gave me a bone stock tune

Bone stock tune and you're turbo? What a pos. Probably lucky it didn't start so you didn't lose your motor. Atomic ftw one more time!!!
