Unable to Read CD's

[DeepUnder]

I have added an X2.3bLite chip into my 1.4Xbox. Works OK flashed ok

When i put my backup in it has a hard time reading the game and sometimes has a hardtime reading an original game. If i try the chip off it reads the original straight up.

Then i turn it back on and it will read the original and then read my backup.
Sometimes if i turn my xbox off and turn it back on it has a hard time reading the backup again

What can i do to fix this

Thanks
