So i installed a FMIC and since i don't have the signal coming from the cold pipe anymore i taped my boost controller signal into the turbo outlet housing. But now the highest i can go is around 8-9 i used to be able to push 10. And i want to push 12. Any idea why i cant push high boost? I have a manual turbo xs boost controller.
