AEM Tru boost

I have a 6 lb spring in my WG and am trying to run 15 lbs of boost, but it doesn't seem to want to go higher than 12 lbs. My duty cycle is from 10-90 and when I set it to 90 I can't seem to go over 12 lbs of boost. Do I need to run a higher spring in the WG to be able to get the tru boost to go over 12 lbs? I thought you could get it to go higher than double the spring pressure not sure though? thanks!

yeah not a 100 % hiv positive but i think double the spring rate is all you can get.

Usually you can only double the spring pressure with out using co2.

Yes you will need to go up on spring pressure.

Why can you only double spring pressure? If your controlling boost reference to the wastegate it seems like you could run infinite boost. I'm sure you guys are correct but can you explain it to me?
