    hey guys I was curious today at what my wastegate spring was set to on my dsm t25 because I've been reading that they are normally set to like ~12psi so I took some vacuum line I had laying around and did a little test. I found out it started to crack at about 10-12psi like I thought but it was fully open at like 28-30 psi, is this normal for an internally gated one?

    because I planned on using this on my build but I don't think I would ever be able to handle 30psi nor do I think a little t25 could even spool that.

    and if you guys are curious how I found out the psi is once I saw it crack I would take off the chuck and out on a tire inflation end and it read the psi.

    thanks guys
