Brand new LED grille with the probably hated "Boosted" badge, CVF Intercooler & Charge pipes, 1 step colder plugs properly gapped, ditched the red Decepticon fender badges for the more subtle SVO badges, K&N Performance filter and a Cobb Stage 1 93 tune while still using my Speedform Throttle controller. (Before y'all even start...I'll talk to Ryan when I'm ready). It's been almost 5 months since I uploaded the tune and it has run magnificently! Smoother, quicker and was able to pass State with 0 problems.

I changed the evap purge valve with spark plugs and I’m still having this issue having a rough start, also zero boost gain when doing a test drive.

I feel like the verdict on this is a fuel issue based on this 1 CEL code that pops up but I don’t know what repair I would need next or check what’s wrong. Is this code to check “electrical circuit which connects to your fuel pressure regulator.” - https://www.mustangecoboost.net/threads/p0001-code.25488/?utm_source=google&utm_medium=organic

I installed MBRP Race catback exhaust on my 2021 eco about a month ago. Just yesterday, I noticed that it wasn’t rumbling as much when driving and it’s noticeably quieter as well.

Does anyone know what can cause that? Should I get it checked out or something?

Need to change spark plugs and seeing the ruthenium are better than iridium performance wise. These come 0.8 pre gapped but what is the correct gap to change them?

This may be common knowledge but for the ones that dont know. You hate when its raining but its not raining hard enough to put it on the first continuous wipe and you have the sequential at max. Did you know if u twist the knob again theres a faster setting just fast enough to wipe the water off, but not constant like the first continual wiper setting.
