Overboost issue

[theretired1]

I have just installed Stinger pimp, external wastegate and electronic boost controller and am working with Jeff Estabon to program. The problem is at this point the electronic boost controller has not been added to program but is installed. On test drive boost shot to 17 we are unsure why when has 8 psi spring. We are looking for any and all ideas
Thanks

Remove the boost controller, run the vac hose to the lower port on the gate so it's running on wastegate spring only. If that doesn't get you 8psi then you've got a stiffer spring than you think, or insufficient flow through your gate (too small, bad wg pipe angle, etc.).
