Heres another log. I did get a 2bar map sensor on the way as well. I will get the A/F gauge hooked up in the next couple nights as well. How is it that I can wire that so I can have that on the datalog as well? I am new to hptuners so I may need a lil help. Thanks!

Resuscitating this thread for benefit of the "troubleshooting" info. Install instructions are always "go right" and don't really help when you come across these types of issues and, being a guy that buys his share of previously owned equipment, these "work throughs" are very helpful. The OP stated that the tune was done by a reputable tuner (not some shady joker), but FFDP and Atomic indicated that the logs have several segments that hadn't been touched that should have been. Atomic also mentioned a possible bypass valve issue.

Did you find this to be strictly an incomplete tuning issue or was there a hardware problem?

Fairly certain this was the issue, but no response from that guy.

First thing I noticed was the map sensor setting if you changed the map you need to up those numbers to match the sensor or it will not read right.

Ahh...yeah, that other thread spells it out pretty well. on a related note, I had a "tuner" like that once...back in 2004, I was his first GTO. A fairly simple H/C & headers...I was barely able to make it to my current tuner's shop without a meltdown (so lean above 2k it had the headers glowing). Apparently the GTO has a different segment structure than the f-body/vette/truck tunes that everyone was accustomed to...or so it was explained.

Thanks for the reply.
