TURNING THE BOOST UP! S15 SILVIA GETS A NEW BOOST CONTROLLER UPGRADE & TEST DRIVE! Turbo Flutter

Here we take a look at the current boost controller setup on the S15 and replace it with a new GFB Atomic Boost Controller to achieve our aim target boost level of 14psi for more power over stock form, safely. We test the boost level on a test drive with success! We also get more turbo flutter and dose sounds due to more pressure and the turbo sounds being more pronounced. Before the previously installed boost controller wasn't doing a good job at this and only 10psi could be achieved. We were able to gain more power by increasing the boost pressure by 4-5psi!
