Is there a problem with the speed 6's not holding boost all the way to redline? I drove 2 of them and at WOT only, it feels like the boost falls off after 4500RPM and the car does not feel as strong as it does below that. As a matter of fact, it feels like my wifes Mazda 3 at that point. Now at half throttle or so, it pulls hard much higher in the RPM range, like up towards the 5500 area.
Is this something in the ECU controlling how much boost it has up top, or is the turbo falling on it's face? I can't see it being the turbo becuase it feels stronger at like half throttle. I'm looking at getting one but if there is no power up top, then I may have to re-think it. If it's just a matter of putting a boost controller on it to make it hold a steady boost, then that's no biggie. It's just wierd that it's only at WOT that it does that. Help me out people!
edit: I found the answer on another site, the ECU opens the WG after 4200RPM if it senses cheap gas(via knock), which the dealers probably do. This thread can be deleted, I didn't see an option to delete it.
