Increasing Wastegate Spring from 1bar to 1.5bar
Guys ...I'm running Turbosmart Pro-Gate 50mm wastegate with 1bar spring ...
My tuner suggested me to add another spring to my wastegate so to make it open later around 1.5bar ...
Will it had any advantages/disadvantages ?

if you are questioning your mechanic, you have the wrong mechanic.
will it have any effect on spool? that depends on your boost control setup.
just make sure you adjust your boost control after you have installed the new spring

i would say either way you are fine.
you can remove the duty cycle in the ViPec so you dont get tapered boost response (when coming onto boost). You run the risk of overshooting/spiking past your desired boost level though. I'm running a 1bar spring, and running 1.5bar boost perfectly.
Up to you!

I run a 1.5 bar spring set in my car and am very happy with it. I have not had a chance to log boost yet but looks like it helps hold 2psi more out the top.
Spool, it would depend on boost controller setup, but normally no. Closed is closed no matter how you look at it.

The whole point when running a solenoid is to keep the WG SHUT LONGER . It does in fact increase spool up.Also running a bigger spring or a second spring will def help maintain boost in the upper rpm's and prevent tapering off. Two different scenarios and facts.

Actually it does kind of matter. The whole point when running a solenoid is to keep the WG SHUT LONGER . It does in fact increase spool up.

I also stated that running a heavier spring will induce higher boost pressure in higher rpms than compared to a lighter spring... So maybe I'm confused as to why you even posted trying to contridict me...
