Your assessment is incorrect. You clearly either didn't read the log, or you don't know what you're talking about. There is definitely evidence in the log showing that the car is not running properly.

I bought this car about a month ago and i wanted to do a cobb stage tune 2 eventually. I bought stage 1+ including the internal/ intake/ turbo inlet. I installed these parts myself. After the install the car was running fine until i blew the turbo seal. I took it to the dealership(stealership) and they put in new turbo/ coil packs and spark plugs. When i picked it up they told me that it needs a tune because of the HPFP. I put the COBB stage map tune on it. That didnt fix it. The car will idle fine for about 10 minutes and it then eventually dies and i get a fuel system too rich in bank 1. Mazda tells me it needs a tune, Cobb tells me its mechanical issue. I need help please!Attached are the logs of it idling. Should i just go back to stock internal?

Your car is running insanely rich for most of that datalog. Your idle AFR should be around 14.7:1. Your car is sitting at at 8.6:1 to under 12.0:1 for most of your log. That's between about 23% and 71% more fuel than the car is supposed to be getting at idle. Additionally, your fuel pressure is elevated. I would expect to see between 400 and 500psi at idle, not 800-1200psi.

To me, this looks like you're either running entirely the wrong tune for the modifications on your car, or you've got a something blocking airflow in the intake tract.

For the moment, there is no reason to remove the fuel pump internals that you have installed. Aftermarket HPFP internals can be run on the OEM tune without problems. Likewise, they can be run on aftermarket tunes without issues.

What *exact* tune map are you running, and what *exact* modifications are on the car?

Have you checked the intake system to see if there is anything blocking airflow?
