Are all 38mm wastegate springs the same size or are they specific to the wastegate? I have a turbonetics evolution 38mm wastegate, and the heaviest spring it comes with will only give me 10psi w/o a controller and 15psi with the controller. If I adjust the controller any higher than 15psi the boost jumps around and starts to blow off prematurely. BTW, a stock wastegate would give about 23psi, but I changed DP's.

OK, if anyone has an extra spring from their wastegate, can they please measure the dimensions for me? Thanks.

I *think* that I have some springs in the garage from my DeltaGate's (I have one on each car), but are you set up like this?

That is how both of my cars are set up and I have lots of adjustability with both cars.

What measurements do you need?

Found the problem, I am using a stock '03 Evo intercooler, and it can't flow enough to keep up with my PT51.
