pressure drop
This could be aided to your advantage though. For example, I have an inner and outer spring of 7psi each for my wastegate. I am going to run a base setting on my stockblock until I get my 370 in. I will be refererncing from the compressor and running off the single 7psi wastegate spring. I am thinking this will net me anywhere from 5-6 which is jsut where I want it. I also have a boost controller that will be installed at a later date with the engine and most likely switching my reference source to after the intercooler. Hope this helps ya and wortht a try instead of getting a new spring depending where your reference is.
