I have been listening to the posts her for a while and the complaint about top end has bothered me. WHen I first got my WRX, I raced my buddy who has a 1998 BMW 540i, it is the 6 speed manual tranny. From a light it was a joke I killed him. At the next light he was going balistic!! (in a cool way, could't believe how fast I was). I told him it was due to the 4 wheel drive that allowed me to launch well and that he would kill me on the highway. I used to have a mustang 5.0 (faster than most other 5.0) that he would walk away from on the highway so I figuerd he would walk on my rex....not so. On the highway we were dead even. He claimed I was passing him but if I was I couldn't tell. We were pinned for a LONG time and I was absolutely puckered!! (11:30 at night on a three lane highway with not another car in sight). I call it dead even. Now with my mods (SPO waste gate controller (MBC) Borla cat back and K&N) I absolutely destroy him on the highway (14.5 lbs of boost). I can't imagine now that I am running at 16 lbs what I would do to him. All this to say that I have not had an issue with top end.
