ok so i get a turbonetics delatagate wastegate with my kit and guy who sold me it tells me it comes with a 7-9 spring but he only seen it do 9-10 psi with the screw all the way up. and i really dont feel like ordering the 2-4 spring cause i will eventually rebuild my engine again with pistons, rods, etc. this summer. oh yeah btw, car just came out of garage for an engine rebuild (stock though). anyone here running the 7-9 spring on stock internals? i have a turbo XS boost controller but i was told i cant use it to limit amount of boost cause it only turns boost up from what the wastegate is set as, right? any advice on what to do anyone?

your safest bet is to just get the 2-4 or 5-7 psi spring
