Default EBoost problems, need help fast

So my car is getting tuned and we can't get the Eboost2 to do just wastegate pressure. It won't go any less than 11.5 or so psi even when set to 0. What can I do? Can anyone help out with suggestions?

Typicly you cannot go under the WG spring size and you cannot go more then 2x the spring. So your max boost right now would be 23psi, your minimum is 11.5 obiously.

SPring is the standard STS spring at I believe 5.5psi. We're shooting for the 8-9psi range.

then try unhooking the wastgate line and run it off teh WG spring and see if that bring the boost down to 5.5, if it does then ur WG was hooked up wrong or the EBoost is broken

If you have the Turbosmart E-boost controller, be sure to read the directions. There are two possible ways to connect an electronic controller. One way versus the other will maximize the vacuum and pressure. The other way is a generalized connection method.

Also, if you have multiple connection running off one source, your variance between v and p will be skewed. I always recommend sourcing the w/g by itself.
