Ha, Looks like I'll be ordering the GM unit soon... also helps to explain some of my fluctuations at the 50% boost range.
....now to devise a way to keep that GM clicker quiet! ...this may sound silly but I'm thinking the cloth and rubber inserts that hold the top of the toiled to the bottom might be a great idea
... I should stick one behind the mount for my LICP also now that I'm thinking about it!

mrfred, I dont have the MAC to compare with, so your probably right about it being a 35 instead of a 36. Also, I do run the AEM solenoid with an inline resistor (10ohm) and my duty is in the low 70's to see 25psi on an otherwise stock Evo IX. It's certainly capable of making more boost, although it does seem to be very touchy. In fact I run almost a flat 72 duty cycle accross the entire rpm range except for the higher rpm range when I get up to around 80. Even slight variance in the duty resulted in very choppy boost. The good news was I already had the solenoid as it was included in my truboost gauge and I've gotten good results from it. I've tuned cars with the GM 3port as well and it works great. Next time I'll probably go that route but the AEM was in my toolbox and I got it to work well. If you have one already you may as well use it. If your in the market to buy one, the GM is better and cheaper.
Did you do your testing with the muffler on or off? I've removed the AEM's muffler and vent back to the intake.

Yep, 30 Hz can be done. tephra may include it in his next ROM patch, or I may do a standalone patch. Still need to discuss with him.

yeah I am still ironing out the details on that one.
I have been running 2x50 loops (instead of 1x48 stock) for a while now, and no downsides.
We can run more smaller loops, or less bigger loops. obviously the tradeoff is exposing yourself to more deadtime of the solenoid - which results in less real wgdc.
