I have a 7PSI spring in my Tial wastegate. How high can I safely push it with a boost controller?

What type of turbo is it?

Assuming all other support mods are in place, you can usually go to 2x maybe 2.5x the waste gate... So roughly 17-18PSI probably? At least thats what I've seen on my turbo (JGS starter kit, T3/04E 50 trim .63 a/r)

I had the same 38mm Tial with the 7psi spring and I ran 20psi at times.
