Installed tuner studio lite to see your msq. Total newbie to this but your 3d maps seem to tell the story.
Are you not using a maf? It has speed density selected.
Use the sliders to move the maps around to see the topography. Look for holes and peaks then figure out why.
You have a very lean mountain in the afr table at 65% load from 1800-2600 rpm, but everywhere else(less load, more load, more rpm) is richer.
On the ign map you have a ditch at low load and rpm with very few data points coming out of it where the rest of the map is very flat. Generally all advance in by 3000rpm (think old school flyweights) and a separate consideration is fuel efficiency by adding timing at light loads (think vacuum advance) that gets pulled out with increasing load. If you are using egr, there is advance of a few degrees when the egr is open and depending on how open it is/duty cycle).
Also, the mostly flat areas don't need many data points so shift more resolution to the area with a lot of change.
Can you upload the stock tune for comparison? Should not need to deviate much from that.
MV8, Hey thanks for looking at this for me. I am running MAP, so the speed density is selected. I don't have an ERG if that helps. This thing is bare bones. I do have an economy box in the program that is set up on my highway cruise. As for the rest of it this is mostly set up by the self-tune on the MS program. The timing map I had a guy from Canada help me when I first set this up and he called safe timing. There is no doubt its leaving HP on the table. I would love to get ahold of a stock tune but where? I can't find really anything about them. I do have a current log but it won't post here.
