Do you have an external wideband?
because of the two stock o2 sensor, just one is a (widerange) AFR sensor, the second one is just a simpler o2 sensor that can detect stoich and nothing more
this one is used just for small post-corrections in closed loop mostly and you won t get an afr value from it in the logs

Negative, no external. I'm referring to the wideband and o2 sensor. On my log the wideband comes in as A/F sensor #1 and the other as o2 sensor #2. What I'm seeing is the wideband reads pretty normal according to the manual, but the #2 sensor top range for rich is .55v and its sitting at .7

they are completely 2 different sensors, with different function and scalings
They aren t comparable and you only must look at "afr actual" calculated from the first lambda only

There's nothing happening that I see to cause the FTs to go up. My FTs look at my perfectly normal AFR and go "screw that, lets max out the LTFT for no reason."

the reason why it creeps up it is because it is told the ecu to inject a certain amount of fuel for that airflow measurement/calculation
but that fuel isn t enough so the ecu adds

Need a maf scaling

Just finished installing Edelbrock SC into a 2017 BRZ PP. I have a leak coming from the coolant surge tank. From what I can tell, it appears that both connectors are leaking. I tried rotating the clamps and moving them in a bit towards the tank, but the leaking is still occurring. None of the other coolant lines are leaking. Maybe I am missing something. Recommendations?

First verify that the surge tank does not have a defect/imperfection or a small split where it's seamed together.
I would also try moving your clamps outward slightly so they are squeezing right next to that raised part on the end of the inlet pipe.
You could get different clamps, worm screw type.
Another thing I personally might try is a dab of pipe thread compound on the inlet pipe then clamp, that may help seal it, just try to do it in a manner so it doesn't get into the system.

This is what fixed my leak.

The supplied Edelbrock house clamps are ridiculously strong. Mine actually made little folds in my EGR solenoid hoses. Try pulling them, residing the house a bit to reseat it, and reclamp right after the barb.

Before I get a shift kit or valve body does any have any tips for the slow shifting after you add the supercharger on the automatic.. I know blah blah.... But when I fix this look out...

Quick question for you guys. Any tips on which coolant to use in the SC loop? All I've seen is the recommendation to use a different color than the vehicles coolant. The Subaru super coolant or whatever is blue so I've been looking around for a good coolant for the SC that's not blue. Engine ice is blue as is the mishimoto liquid chill. The Evans waterless coolant is yellow but I have no experience with it so I don't know how well it cools or if it would agree with the Edelbrock internals. Any help or tips are appreciated!

just dont go cheap and you'll be fine. I've got Prestone at 15% right now, but it never freezes here.

Edelbrock simply calls for 50/50 coolant/distilled water mix. The only real reason to use a different color is to quickly identify which system is leaking should you develop one. Just so I didn't have to have 2 different brands, I've been using the Subaru blue in mine for 3 years now and no issues.

Thanks @BirdTRD. That's what I was thinking about doing. Just didn't know if there was any other high quality coolants that did happen to be a different color

And thanks @B T
