My car has been actin weird lately. My car will only hit about .2 kg/cm^2 in first gear, but in second and third gear it'll hit full boost of 1.3kg/cm^2 but at about 4800rpms which is a little late. Also, when I drop it from 4th to 3rd and floor it, it won't hit full boost, as if the clutch was slipping, but I don't think thats the problem, although it's possible. I have to floor it at anything below 4k for the car to hit full boost. Like if I drop it from 4th to 3rd, and it's at 5k and I floor it, I'll boost about .3-.4 kg/cm^2. Also, my bov isn't quite as loud as it used to be, I've checked everywhere for boost leaks and that doesn't seem to be the problem since I can hold full boost when I hit it. Any suggestions?
