i have a tial 38mm wastegate with a 7psi spring in it.. and i was wondering if it is going to be safe if i would go more than 20psi on that spring.. the reason why i am asking that is because.. i was told from my tuner that it is not good to really go more than double more than your spring in your wastegate.. and he told me to get a 10 or 12 psi spring to i could be pushing more in the 20+ psi range in my lsvtec car.. but what i am asking is... do i really need to change it out or i am going to buy another spring.. i am lost cause i want not to have boost creeps or spikes.. i am wanting to run correctly.. thanks..

i'd do what he said get a 10 or 12 psi spring
