Now heres the problem....I have no idea what kind of boost it's going to take to run the power I want. I think around 11.5 but man I dont know!

Ok I have a Tial wastegate and BOV. I have a 8.5 lb spring in my wastegate, and i have no clue what one is in my BOV, HOWEVER it is working fine for my 8.5 lbs of boost and it was working fine when i spiked at 16 on the dyno.

Now i'm going to be running more boost, Ray at mcnews is re-tuning me and we are putting a manual boost controller in. Do I need to change out any springs in the WG or BOV?

Here is the TIAL spring chart

no. unless you want to go lower than your current one of 8.5 which I dont see why you would want to. the boost controller wont be able to go below what you have the spring set at, however it will be able to go higher, and higher and higher and higher and higher until you got it where you want it
