I am going to wait until my HPTuners Pro with my LC1 wideband shows up in a couple days before I restart. I will be converting my other laptop to the tuning laptop since my buddy texted me this morning and said he can't afford to fix the laptop he "dropped"....btw "dropped" actually meant he left it unattended somewhere for a few minutes and it got stolen.

Oh well, live and learn and don't lend your stuff out unless you can really trust who has it...my problem is I trust everyone too damn much.

Back to the topic at hand, for clarification, the LY6 has been converted to non-phaser with LS2 chain and cover, Lingenfelter 58x to 24x conversion box and LS2 cam sensor. The PCM I believe is from a 1999 as the harness is from PSI Conversion in Toms River, NJ. Quality stuff but I think he just did a general flash and may have missed the mark for the injectors, etc...

I have also heard issues with the Lingenfelter MAF needing a screen or being clocked a certain way to actually read properly. I am going to plug the HPTuners in when I get it set up and just read the basics to see where I am at. I will lean on everyone else once I get the goods.

Thanks for your help and interest thus far! I am very interested in becoming proficient at tuning. I hate having to go somewhere for something without a solid knowledge of it myself.
