AEM Tru boost help Alright, how the heck do you program this thing? I read the manual but it sux! I am sick of running off the spring because of the inconsistent power. I want to set it where i am running 12psi all the time! Is there a write up somewhere how to program this or can someone help me out? 
They are probably one of the most un-user friendly boost controllers I've used.
You hold down both buttons for about 3-5 seconds. After that it goes in to the programming mode. You push and hold either the left or right button for 2 seconds each to page threw the setup menu.
Its awkward but not to bad once you get the hang of it. Remember you can't set the boost controller to any particular boost. Instead you give it a duty cycle for it to run the waste gate. default and lowest you can go with the tru boost is 10%. The tru boost spring pressure setting seems to be nothing more than gate pressure.
A very rough way of thinking about it is 0% should be on the spring minus what you loose threw the intercooler and 100% should be twice the spring - what you loose.
So if at 0% you make 5 pounds 50% should make 7.5lbs and 100% should make 10psi. Again this is a rough estimate and your results may vary.

Yes, its very tricky! So if i have an 8lb spring i will run 14psi at 100%
Also how do you get it to display the PSI?
Dont you have to sent the DC to get your target then mess with the crank presser setting to keep the boost at the desired level?
I am sure i will have more questions on the way
Thanks for your help!
