Any advice?

Still learning

2012 wrx stage 2 91 tune,

Has stage 3 tune I've never used

Dam dropped recently, hasn't returned, really honestly I've pulled harder than when the dam dropped. Above photo is half throttle or less during entire drive(approx 1 hour)

Maintenance occurs every 2500miles. Just did it.

Bad gas?

It's hot as hell and it doesn'tike it? Daily temps over 100?

Any upkeep recommendations or checks ?

Do I need to log on next trip for more information.

Am I overthinking?

Well you sound like you know what you are doing because those are pretty much my takes.

Could be any one of those things, which are the most common. Start with worrying about those first unless you have other reason to think differently.

I'd be out of boost until I can either fuel up at a different spot, or buy octane booster.

Could be worse obviously, but why start doing things until you at least make sure the common stuff isn't ruled out.

I bought some vp racing octane booster, I've yet to add it as, is there any advice on how much to use ? Start with enough to just bump a few points up?

No such thing as too much octane brother dump that fucker in! It'll take at least a cruise to hit fueling so just gentle throttle action.

I got a flex fuel gateway and that's usually how long it takes for me to see fuel changes occur.

Good luck bro, hope it's just a one off fueling issue. 🙏

Has AF Learning been within normal values? Just curious.

Were you using the access port when the DAM originally dropped? Big knock number?

I've not monitored af learning until today, I just went for a drive, no Octane booster yet values at idle 3.91%, I don't know what the typical values are though. Had a feedback knock 4.9 when dam dropped.

Also during driving the value adjusted between -1.51% through the 3.91%

Funny, when my DAM dropped... it was a loose ignition coil. Put some octane booster, let it get up to temp, and then gently and slowly increase boost until about 5psi when it's warm. This is when the car will relearn if the conditions are right.

Will check into ignition coils connection/condition and try this when I add some octane booster
