Its a 30 day trial and you have to buy it after that period but worth the bucks. Then you have no more reason to skip one of the best HD2 Roms ever.

I knew that I would receive this answer. But trust me, I've tried Poweramp before and it's a complete crap compared to the in-built player with its in-built equalizer in Energy's rom. I know what I am saying. It's strange how people prefer to use some paid and completely unnecessary solutions since they already have better ones, already in-built in their systems.

which energy rom, can you post link it?

I've no more low soud experience with bluetooth, that's cool ! I need it every time I take my car.
However, I have got a black screen with an incoming call, when my phone was pluged into my pc (without sd mounted), I had to press a button to wakeup the screen.
I didn't set up any "perfomance options", I have 245-998Mhz smartassV2, CFQ, no KSM, no Zram. I used them before (on v2.2) but my phone works better without...

I experiment also some reboots only when I have a bad network coverage (2 bars or less) and freezes only in my car, when I use the gps (Icoyote) with the sd mounted on usb (mass storage).

And I've noticed a curious comportment when I activate the mass storage with Icoyote or Maps (naviagtion) running, both apps seem restart ! Maps re-calculates the route and Icoyote restarts.
I've no remember of this when I used the sys@NAND install.

Thanks for trying to answer me.

However my phone is installed in front of a cooled air nozzle...
I thought it was related to T° too but it never exceeded the 40°
I don't remember the T° of throttling and that of reboot, I've read it before but... (40 and 50 ???)
It's only freezes happend in my car (and one time when I used the GPS for less than a minute), reboots are less frequent since I've made a fresh install and don't touch performance options.
Are you using KSM and/or Zram and have no issue Tytung ?
But as I said, a bad network coverage increase the risk of reboot. Maybe no enought power for CPU ?

From NYLimited at XDA --

There are many factors which create lag in an Android device but the number 1 biggest factor is working memory (RAM) where your apps get loaded,

This is why running many apps at the same time or running very large apps (e.g. Google Maps) will make the phone lag afterwards. The large app will use up all the available memory and even though you return to the main "desktop" the app is not completely closed or removed from memory.

Starting another app will require Android to completely flush one or more no longer used apps from RAM and load the new one - now you have lag.

The HD2's NAND speed is also pretty slow (roughly equal to a Class 4 SD Card) so even loading a new app can take time.

What can you do about it? Well, you cannot eliminate lag 100% because the HD2 has limited amount of RAM. The only way to totally eliminate lag is to get another device with 2 GB of RAM. Having said that there are things you can do to make lag manageable most of the time.

First and foremost is controlling how Android makes available RAM. This is accomplished via the MIN FREE settings. Tytung includes default settings for min free via a script which is located in the /system/etc/init.d folder (99_lowmemorykiller). If this file is removed (deleted) you can set your own min free values via many apps, such as ROM Toolbox. Using an aggressive setting will make Android react faster and keep more free memory more often, thus some of the lag is eliminated.
