Well we ran into some issues. First off. The car is making like 768/745 @14psi and 22* timing. Its spikes to 14psi and falls off to 12. Which is one issue. The other is, we out the eboost2 set point to a value of 70 cuz nothing about 20 was changing boost. It finally spiked to 23psi from 4800-6100 and it made 860/730 really fast. But we could never get the boost controller to work again. Im happy but pissed off and confused at the same time..

It's probably going to be slightly different on every car, but with mine I have a 7.5# spring in the gate and achieve a fairly flat curve of 16-16.5 psi with a sensitivity of 20 (default), GP of 12.0, and SP of 52. I'm using method one as well. Make sure to keep the gate pressure 3psi or more below what the SP will achieve or you will just have a spike to that GP number. Hope that helps.
Edit: 9lb spring in the gate. Not 7.5

Had to double check what springs I didn't have in it... I was wrong. The 9lb setup is in it right now. I guess my memory from 13 months ago isn't as good as I thought! It runs 7 psi when I have the cutout closed and 8 psi open with the boost controller off.

Thanks for the video joey.
11psi wastegate spring, peaks to 14 and falls off around 12.5-13.5
we tried a few different things. I tried the standard SP-20, GP-15 and left the sensitivity stock. No change in boost pressure. We then bumped the SP value to 45 and adjusted GP accordingly, still got the same boost. So we said **** it and took the SP value to 70 and we hit 23psi from 4800rpm tot 6100rpm and the car made 860whp real fast. So we thought we got it figured out. So we then bumped down the SP to 65 and then it went right back to 14psi and could never get it to respond again... so Im going to try to re plumb the gates to method 2 and see what that does.
