Tial 38mm wastegate with only one spring?

[wee-jo]

So the garage working on my car was setting up the wastegate to take it for a spin. They noticed that it only had the one spring. The spring was a large green one, which, judging by tial's wastegate spring graph is .9 bar.

Should there be a small and large spring or just the one spring? The model of wastegate is the f38, the previous model down from the new v band shape one.

The F38 actually only comes with one spring

The MV series usually come with two

as above mine only has one spring

Although one question, mine has the blue 0.6 bar spring in, yet without the boost controller set up it only hit 0.4 bar, any idea why?

Springs vary, depending on what boost pressure they are desired to hold. You can run one spring or two.
