Well after finally getting some time with a computer to review my datalogs from the Holley ECU, I made some modifications to the timing table and the idle settings a bit. My timing that the engine was referencing at WOT (mostly the top two rows of the pictured tables) were set very conservative. I also upped the timing at idle to smooth it out and not want to die when shifting into gear. Essentially, before max timing was 32* and I upped it to 35*. See how this goes, may take it to 36* next time depending on knock sensor logs if it is reading any pings. I also added several degrees in the midrange and lowered the rpm to max advance timing to around 3500 to gain some midrange acceleration that was lacking.
(Note: I have the small format table enabled so I don't have top make so many cell changes. It automatically converts the small table to a smoothed large table. This setup has so much ability for fine tuning it is amazing.)

The datalogging ability of this system is incredible. Each datalog contains a record of every sensor reading and every commanded parameter that can be toggled on or off, and you flip datalog pages tailored with readings for tuning at idle zones, boost controlled zones, etc. All very easy to use and navigate. When in datalog review or in real time engine running, when you look at your tuning table parameters, a glow dot appears over top of the table cell that the ecm was referencing at that particular instant. Very easy to see where changes are needed and very easy for your engine to tell you what it wants.
