Hi guys,
I have just started dipping my toes into tuning on my 2005 Monte Carlo SS with the 3.8L SC L67 engine. I have been reading and watching videos, and tonight I went and did a scan for LTFT+STFT tuning. I don't have my wideband installed yet, so as of now I am just trying to tune idle and low throttle fuel trims. I went ahead and disconnected my MAF sensor, however I didn't disable PE as advised by Goat Rope Garage and a few others. I have uploaded my log file below.

The first thing that stands out to me is my LTFT+STFT table is waaayyy off, assuming I have it set up correctly of course. My understanding is that I now need to multiply by half those values into my Primary VE vs. RPM vs. MAP table and then do it all again, is that correct? Is there anything else I should do? Did I do something wrong with my table or something?
