attention EBC guys..
as mine keeps over-boosting via DME i want to know how yours are set up.
- Boost controller?
- Dualport or single?
- at what psi is yours set to regulate boost
- What's your target boost pressure?
for example, mine:
- eBoost2
- Single port
- 9psi (now)
- 17psi
Thanks a lot!

I have Tial 38 in dual port mode with Eboost Street
My Eboost street has the following settings which is now somewhat fine tuned after today to try to reach peak and steady state of about 14.5psi
SP1 - 40 (set point)
GP1 - 5.3 (gate pressure)
Sn - 20 (sensitivity)
with the set point at 25 the steady state boost is 12 psi, but the gate pressure was fine at 8.0, so to my surprise I had to lower the gate pressure in order to avoid overshoot when I raised the set point. Not sure why this is, when you figure it out let me know.
What sensitivity settings have you tried and what effect has it had?
Try lowering your gate pressure to 5psi and see how it runs and then work up slowly from there, you can see that I didn't get too far above 5psi. I was thinking of trying to raise the sensitivity and the gate pressure by a bit to see if that kept the spike down.

Thanks guys!
i now have my GP on 0 and i have no spiking issues. it builds boost good and the wastegate doesn't open to early. quite weird i think.
I've had mine at a few places but i don't notice to much of a difference. 20 is factory so now i've left it there.
I think you need a dyno to adjust the sensitivity because you need to be logging real time not snips what my data logger does so it's not a jagged line.

If you are running factory single port, 0GP is probably right since it starts opening at around 3 PSI depending on how worn the spring is. It really is a small diameter weak spring.

I've got a TiAL 38mm with i think it's a ~9 psi spring as that what is boosts to when it's on single port mode with no boost controller.
