Mystery Codes

I was using the TGO RPO decoder and when I typed in a few of my rpo's it said they were invalid but they are on my sheet. Does anyone know why? The codes are, E6N,
----------
WS5, WS8, WU1. can someone tell me why these are on my rpo sheet but I cant find out what they are? Sorry about the two posts. My computer glitched.

Re: Mystery Codes

Another question I have is...It says I have option code GT4 which is 3.73 rear gears, but on here it lists 3.42's as standard equiptment and 3.73's with the G92, but I dont have G92 so I'm confused

Re: Mystery Codes

i didn't see any of the codes you mentioned at gm rpo codes site. i want to join, i'm looking for D67, E92 and R8B
edit: i found e92, it's dynamic side impact - delete. but the problem is that i still don't know what it means.
