I would say JGS 40mm units would work perfect for you. Also they are very affordable. Contact Modular Turbo for a good deal on them! The spring that is in the wastegate is a 7lb spring and they also come with a 10 lb spring. I love mine no creep at all.

2 38mms should be fine if you want to run atleast X amount of boost all the time you need a spring a littler lower than X. The spring basically provides the minimum amount of boost you can run ie you cant have a 10psi spring and want to run 8.

Im not sure on a twin setup, I would imagine the pressures would be combined so 2 WGs at 5 psi would probably equal 10psi(I would say closer to 9ish). But im really not 100% on that one...

Yeah it works the opposite of what you said. If you want to run 10 psi then you want twin 10 psi springs. Each gate works seperately and they will have a combined pressure as a reference. Where you reference the gate will change it alittle bit, but get the spring that is the base pressure you want to run.
