Small updates

Car was running pretty lean in boost, way off target AFR



Decided to do some troubleshooting, thinking maybe my fuel filter not being changed in awhile was causing a drop in fuel pressure. So i swapped that out



it was a little dirty, but not horrible. It didn't seem to help, as I was still running lean. Next up was a boost leak test, and sure enough I had a pretty massive leak at the FPR nipple



Not sure how it got loose, but the hose clamp was way too loose. It only seemed to hiss above 15 psi, but at 30 psi it was quite a leak.

Finally figured out my lean issue.

Turns out, my Walbro 450 started to go bad. It could not keep up with fueling demands at high boost. I swapped it out for another one, and problem solved
