Hey guys I did a few google searches and checked other forums and I hear some people talking about it, but nothing was solid so I wanted to post to ask if anyone knows if this is normal.
My 2011 WRX has just under 74000kms on it, no mods, bone stock. When I go full throttle in 1st i dont notice anything, in second usually nothing either but in 3rd there is a slight tiny little power dip just before 4000 rpms for about a millisecond, my fiance is a frequent passenger and she says shes notices that all the time and thinks its normal. Now I normally don't go full throttle in 4th or 5th unless i am on the highway trying to pass (which i am then paying attention to the road more so then anything else) but i usually ease into it. But i noticed tonight driving that when I go FT i notice a 1-1.5 second power dip around 4000 RPMS the turbo sounds like it just pauses and then it jumps up past 4000 rpms and i can hear the turbo screaming. No engine light no sputter no weird noises. Is this normal and i've just lost my mind or is this a sign to bad things to come??
