Tell me if it fixes your problem.
One quick way to test is to run on terminal:
su cat /proc/overclock/max_rate
If it works, it'll also fix your AppInj problem.
As for LGEmail.apk, it will be in my next release then. I noticed it's on pays ROM so maybe this is why you don't have lags there.
Since Nova v0 I removed LGEmail.apk.
