Car runs great, on3 kit 70mm turbo

The car will hit 9 psi just perfect, as soon as wastegate opens it drops to 5 lbs or so and doesnt really creep up any higher than that, could be

Just running big blue spring in the wastegate

Only vacuum source I can use is from the vacuum tree, Im running a box upper and theres only one provision for vacuum on it, so that is running to the vacuum tree, from the vacuum tree I have vacuum going to the fpr, wastegate, and bov

Now I know the wastegate is supposed to have the cleanest vacuum source, but this is what I have to work with

Let me know what you guys think, easiest thing to do right now is add the weakest spring into the blue one

Thanks a ton

I tapped into the compressor housing of the turbo with an 1/8 barb fitting, a wastegate will work off vacuum, but better off pressure

Search for Firemanwill's thread on "boost creep". He had the same issue not too long ago.
