i have a turbo on my car. i was woundering if i have a 7 psi spring in my wastegate and i use a boost controller, can i boost higher than 7 psi or would i have to get a spring that could boost more? just woundering. i know not to go so high on a stock engine but i just like to know.

 

yea a boost controler will allow you to go higher then 7 psi but no lower
