newbie tuner Ok so I just got hp tuners today, previously installed lt's ory, and lid. Car is running supper rich as of right now. how can i tune this down in hp tuners. Do i just adjust the stoich afr? or is it to do with the maf. If it is the maf please give me something to work with as far as knowledge dont just say i need to adjust it.
you're in for a rude awakening if you think tuning is just something you can dive into with out research.
you can hack your VE tables if you want, but thats a half-assed way to do it.
it's been a while since i messed with HPTuners on a LS car. But you pretty much want to reset/learn your fuel trims, dial in your MAF transfer function, log/dial in the VE tables, then WOT tuning. You're going to want to log AFR if you plan on doing WOT tuning.

Not to sound like an *** but it seems like you have a lot more reading to do. Basically, you will need to dial in your VE and MAF tables for the mods you have done to your car. The best way to do this is with a wideband and from there you log some data with the scanner and correct the tables where needed.

i agree i do need to read more. i was just looking to be pointed in the right direction for doing this tune, and you guys have helped. another noob question, whats the advantages of wideband over stock o2
Here is another good resource. http://ls1tuningguide.com/index.php
The wideband will be a lot more accurate especially when tuning WOT. The stock narrowbands are designed to target for stoich (generally 14.7:1) and they aren't very reliable for anything other than stoich.
