So I'm thinking I have a boost leak somewhere because my turbo sounds like a jet taking off when it spools up and it's not pulling evenly through the rpms. I notice a lot in 3rd getting on the freeway. The car will start to pull and then it will pull really hard (normally around 10psi) and will sometimes hesitate at high rpms. In first and second I can here what seems to be the turbo spooling but normally don't see or feel any boost until 3rd and through this gear and 4th it screams. I can get the car to boost in 2nd but I have to floor it...makes me think I have a leak somewhere. Are there any other causes for this issue? Plus I think I'm running a little lean
 My wideband normally is around 14 or so but have noticed it sometimes running around 15. Man it would be nice to find someone in Ohio with some st205 experience....

I'll take the car for a spin tonight and see what the wideband says under boost and check for leaks. At idle the wideband normally reads around 14:1, upper 13's. The other day after boosting and slowing to a stop it was around 15 at idle, but only for a little bit. Thanks guys
