If you are getting 11volts to the L terminal, that is causing the issue.

Default ls3 overcharging

Hey Andrew thanks it's been a battle to get a response from fi-tech support, I would like to just put a resistor in that feed to lower the voltage but this system is warrantied from them and I don't want to affect that,I also read some info that the d terminal is suppose to be used on corvettes only any thought's ?

You can wire the alternator without having to go through the fitech.
