i have a turbonetics evolution gate and made 460 with it, but couldnt make more than 25psi, im looking to run 30-35 psi next season around 600 - 650 whp looking to see if i need to upgrade the wastegate to hold the boost. im told the biggest spring made for that WG is 13 psi, i was running the 9 psi spring. im running a dual stage boost controller, i want to run 18-20 psi low boost and 30-35 high boost.

 

does that gate let you combine springs like the tials to rais boost level?

 

im not sure, but people have told me no. i may have to look into it more
