hi all. when i change gear i got a whoosh sound. i have changed the dv to a forge. the car is running 10 times better. the noise seems to be coming from around the front manifold area. i have checked all pipes i can and there fine.
i have heard a small whoosh noise is normal. would it come from this area. i do get a tiny hesitation every now and again but it could be possible turbo lag
thanks
