Safe HPT Pro tuning options without a wideband installed?
I should be receiving my bundle from SDPC today (HPT Pro, Tuning School Beginners Course, AEM Failsafe Wideband) and am going to load the software and get going on the course. I plan to study the entire course but as my welding equipment is in southern California it will be a while until I install my wideband. I plan to first remove the CAGS and all the codes from my AIR removal and my long tube install. After that I plan to modify my fans to keep the engine running cooler. Is there anything else I can safely get into before having the wideband as I probably won't get that installed for another month or two?

Came home to find the Fed Ex door slip on my door. Arghh! Now to see if they will let me pick it up later at the distribution center or if they can drop off tomorrow. If not its ok not the end of the world I'll be putting on my chrs1313 ram air tomorrow so that will satisfy the LS1 cravings for the weekend at least.

No need to weld a bung, I always install the wideband in place of the RF O2 sensor. Also set the open loop table to 1.00 at operating temp (all rows of the table).
Set your PE to what you want, then use the AFR Error histogram to dial in your AFR. Don't forget to reset the fuel trims before tuning.

If that is the case I could get my wideband hooked up this weekend as I was going to wait until I could get back down to socal to my welding setup to weld the bung on. Will there be any ill effects to having no O2 sensor on one bung? Would there be any benefit to welding an additional bung down the road downstream of the O2 and then running two O2s again and one wideband?

Would there be any point to leaving the other O2 sensor in or should I just take that one out too and screw in the cap that TSP provides for their header bungs? As the AEM wideband will also be connected to a gauge that will be on my pillar pod running full time will this affect anything? To clarify I am looking to leave the wideband in not just when I am tuning as most of my tuning especially in the beginning will be all "street" tuning.

Using an existing bung is a good solution for tuning, but not for a full time wideband gauge. Like Russ K mentioned, you will have closed loop disabled during tuning so the front o2 sensors will not be used, but when done tuning, closed loop should be re-enabled and you would want both o2 sensors back in service.
I would go ahead and use an existing hole for now to tune with, then when you get to your welding shop, add a bung and move wideband to the new location and put stock back where it belongs.

Just make sure you don't go back closed loop without having the narrowband O2 sensor back in. The wideband installed in the front O2 location is just for open loop tuning. Also make sure to clear your fuel trims in the scanner before you start logging with the wideband for the VE and MAF calibrations.
