couple of short pulls to get duty cycles for gear dependent and I full pull

Thank you. What duty cycles are shown?

solenoid type- Normally closed

50% = 15
60% = 18
70% = 21
75% = 25.5
78% = 28
80% = 31

87% = 34 (full pull duty cycle)

this car has twin tial 44mm gates and made 13psi when duty cycle was 40% or less, and boost was holding within .5 psi for the pulls untill we got above 30 psi(we ran out of turbo)

Running similar tests with either the AEM or Apex-i solenoids this weekend.

I will be doing an AEM solenoid here in a couple of days.

All of my AEM EMS buddies usually don't like the GM solenoid because it is unstable, but I still want to try 1 to see if it works better with the s300 than it does with EMS

The gm soleniod works fine, its just that if something goes wrong you get infinity boost..

Well, I guess boost cut function saves you from this or doesn't it?

what freq did you run the profec spec2 solenoid at

judging by the age of the post, 2006, i dont think the frequency option was in that version. i may be wrong though.
