Spring Rate set at 3 lbs

Duty Cycle A set at 60% = ~12.5 psi
Duty Cycle B set at 65% = ~14.5 psi

The one thing I've noticed with TruBoost is boost spike at initial WOT. I've seen, with above mentioned settings, initial spikes upto 15.5 psi when using Duty Cycle A and 17.2 psi when using Duty Cycle B.

These spikes last less than a second, nevertheless, it's annoying.

I have the same issue with my Tru-boost. Had it set at 17psi and it would spike to 21psi at WOT. It would only last for a second but it was enough for the AEM to hit the fuel cut, which is very annoying. I was using it on an E16G setup, went back to the manual boost controller to fix the problem.

I have similar settings on the TRU BOOST as simace, not too much different. I used to have some of the boost spikes you guys are talking about when jamming into WOT, but ever since the EMS went in, i haven't had any spikes at all. I like it, i'll keep it!

I dont remember my setting off hand but I run 11 psi for one setting and 14.5 psi for the 2nd setting. I'll check the duty cycle when I get a chance.

haven't had any problems with spiking on mine.

4psi, set to 16psi. - 13T no spike

Front 16G in and controller turned off 13psi, still no spiking.

9bs are so small it is hard for them not to spike boost comes on so freaking fast. larger turbos have a much slower kick in time.

Tru boost rocks!
