Can someone look at my idle and cruise logs and tell me how everything looks and if needed, what adjustments i should make. To save you the trouble, i only have kelfords 272 installed and a full 3in exhaust. Everything else pretty much stock. So far, i got my fuel trips and airflow per rev in check and used the mafcomp adjust tool for cruise.

Does the car always run around 206-210? What T-stat do you have installed?

After the fan kicks in, it drops to 200. i have a 180 degree thermostat that i got from orileys. I've always ran around 200 - 210. Never overheats. recently did a full timing kit as well including water pump, thermostat, and nothing changed temperature wise. Needle stays halfway all the time.
 
in your mafcomp tab i would lower 200hz to -2.3%, 250hz to -0.8%, 300hz to -1.6%
and i would also unclick the box checked at the bottom of the mafcomp tab.
Un-click the Disable Maf compension w/ SD operation box. you are not running speed density and you need maf compensation.
your airflowperrev is at about .26 should be .25 which maybe affecting the LTFTlow which is calling for more deadtime to get your idle closer. add more deadtime until your LTFTlow hovers around 0.0

your isc doesn't go to 30 at idle. it should unless your rad or heater fans are on.
your alternator is low volts 11-13v, but maybe your fans are on. low volts cause tuning problems. you want to see 13.5-14v when cruising.
