Flex fuel sensor + wastegate spring
For those guys running the flex fuel sensor. What wastegate spring are yor running (or springs if dual wastegate). Im just trying to figure out if there is a spring that will work for both low and high boost when the flex fuel sensor transitions. If I have to switch wastegate springs to achieve high boost then I really dont find an use for the flex fuel sensor. looking to run 15-16 psi on 91 pump. and 30+ on e85. Thanks guys

Exactly. If you want to run a ton of boost you dont need a big wastegate because you need to direct more exhaust to the turbine. So no need to be able to vet a ton of exhaust gases.
I have twin 44mm gates and can run 8lbs with no creep to redline.

Sweet thanks guys. I have a dual gate short runner manifold. So it sounds like I can run 1 bar springs in both for pump gas and base boost with no creep. Then use the boost controller to turn up the boost 30+ on e85 on my pt6766. With the wg being able to open fine with the flex fuel sensor doing its adjustments. If not can someone correct me. Thanks again.
