08 WRX boost spike question
Hey guys. Today i was slowly accelerating on the highway and i felt my car stutter and drop about 500 rpm and catch back up an instant after. I tried to re-enact the situation a few times and i couldnt do it. However, while i was playing around i noticed that if i fully accelerate in 4th or 5th gear starting at about 3k-3.5k rpms my car would over boost to about 22/23 psi(tuned to 19 psi). I got these readings on my accessport and on my boost gauge. I have a bigger tmic, intake, high flow downpipe, and catback installed. I also got my car pro tuned with all of these mods in place and my car has been running beautifully for the past year. I was wondering if anyone had any ideas on what could randomly start causing issues like this. I gave my boost hoses a quick once over but it was getting dark by the time i got home and i also tried cleaning my maf sensor. Thanks in advance!
