So, I know I'm a newb (please don't judge me) haha
basicaly I have a 03 wrx which has had lots of work (before me) the car has an Apex-i boost controller (I have no idea how this works)
i tend not to mess around with it and is set to 0 but recently my car is holding less and less boost and is a lot slower than usual, last night I tried to turn the boost up and found that this has made it much slower!
The car also has a HKS bov I'm noticing in getting more of a 'chatter' these days than a dump/tshhhhhh noise the car is definitely down on power but doesn't smoke or anything dose use a bit of oil (2 top ups in 7k)
what is going on? Any help welcome
cheers Chris.
