i have a couple of non serious questions to ask, i know a decent amount of subaru's especially my 04 wrx with 84XXX milles but i suppose u can never know everything.
mods= highflow catted 3in downpipe and its on a stage 2 93oct AP V1 tune
1. recently i have had a weird almost like squecky toy sound out of my exhaust when i rev it up and as it goes back to idle it will squeek also when i shut it off it squeeks? again nothing serious just rather annoying lol
2. recently i noticed it seems like im loosing boost somewhere i'm quite confident i'm not but yet last time i checked i was running 14.8psi in 4th year and now it seems like it hit 13psi and drops off using the AP V1 that is.
i know last time i checked it i was in the mountains? but didn't think elevation would screw with an electronically controlled
again neither seems serious just some things i wanted to know if you guys had a min. thanks
