I have a 2005 wrx with 2 problems

1. When I got it the mapper put on the receipt that the actuator bracket was flexing and a standard would be preferable. It had a boost spike on the old FORGED one. I have now replaced this with a standard second hand one and full boost isn’t coming in till 4.5k then it kicks into life. Is this right for a td04?

2. My driver side window has stopped working. All others work from the driver door. Anyone got a fix?

Thanks

 

Definitely not right at 4k.
I've had 2 mapped and decatted td04 and they should go like a stabbed rat.
I'm not totally up on exact rpms but I would say between 2500 and 3000.
Are there any other mods?
Exhaust?

 

Can`t you contact the mapper and ask them?
