Which EBC? AEM TruBoost or Greddy Profec B Spec II?
What is your crack pressure setting, I am running it at 11 and the spike is 1 psi over my setting and it spools hard. I also have my alarm at 1 psi over. I have only overboosted once and it reset immediatley to wastegate pressure. The only reason I did was because I forgot to go to my B setting one morning when it was really cold. I have heard of people running like 5-9 as the CrP, I really don't see how this can help when the spring is what 11.5?
The spring pressure used to be called GAE crack pressure. This value according to AEM is supposed to be when the wastegate starts to open. 11.5-12psi is when the gate is fully open and the turbo is full spool. There are instructions on the AEM method of determining crack pressure which is why people have the numbers they do.

your right, sry. profec e-01 is the one that has the rpm stuff. no experience with either profec.
I think I ended up somewhere around 7.3-8.5 or so with 62 cold 64 hot. Have you accessed the peak hold feature or are you eyeballing the spike?

Another option, although much more pricey, is the Turbosmart e-Boost 2. It is a gauge style, and uses an AEM style solenoid. It can hold up to 6 boost maps, and can be wired in to control vs. RPM. You can set a boost point for every 500 rpm point, and it interpolates between the points. . .
You can use this feature to spool quickly without a large boost spike, while still holding well at higher RPM. . .

Link to AEM's instructions on setting up truboost crack pressure. If your happy with your settings

Also, should be noted. I control the solenoid with my ECU now. I have rpm dependent control and closed loop correction abilities.
