Ok, so I posted a thread at EGR Delete 02 WRX - NASIOC


it talked about how I broke the fuel vapor switch, similar to the one below:





Then somone posted a graphic about how the system works, and explained that I actually broke the switch.








I found some other threads where people had actually done this for a MOD, I don't know why but I guess it's a mod... Anyways, I did it to my car too! It threw code p0444

Here's the mod pic:






The car ran alright, but it experienced some hesitation I think due to crazy fuel mixtures and not being tuned. I put it back together, and added a nifty aircraft fuel line from our ultralight. It's nifty 80's neon green lol, but it's STRONG. Aircraft parts on a subaru, now that's sexy.








So after a couple of hours, and testing.. this mod is useless unless your tuned IMO, and will just make your car run like dog snaps. However, I would think that if I was tuned, I might see a .000001% hp/tq increase--- but here's the kicker

is the fuel vapor warm?? Isn't fuel vapor actually more explosive than the gas itself?? So by removing this, I actually lose horsepower regardless of tuning, because there is less explosive chemicals in the air mixture...


Anyone else mess with this or have experience??/
