well as for my last post you know that i have installed my TYpes and it wasnt working out very well recirc style. I put the stocker back in. So today i attempted to try VTA . I plugged the intake to the turbo ,adapter side to the IC and vaccum line connected. So i drove around for a little i could smell a heavy fuel smell and i could hear a leak a low speeds and sometimes idle. THIS THING IS FRIGGIN LOUD LOL. anyway i am going back to the stocker one. I probably am going to pick up the dejon IC and then install my UTEC. For now both REcirc and VTA have not worked out . However I do have both springs in.Ill try the one spring mod.

 

Is it compressor surge, or flutter that made you switch. I adjusted mine with both springs but connected the lower vacuum, so that it would still whistle. But it flutter under very low pressure changes.
