I would recommend you jump up the the xda forum under Rev General and there is a couple of threads covering the type of changes you have made (from what I remember the title is about specific changes to the phone, I will look for a link for you and edit in).
They have specific lists of the upgrades and the benchmark tests. They also comment on how the phone performs. Good information, I am sure you will find a fix to use.

There is also some posts about "Tweaks" in the "Rev Development" section.
