My C5 is a 2000 as well. I've only changed the primary VE table and as noted running closed loop with LTFTs enabled. Car has ported 243 heads, 228/230 112 LSA cam, Weiand/Lingenfelter intake manifold, log tube headers without cats, and Corsa exhaust. I'm pretty happy with the tune but am looking to add the Vararam intake in 2016 which will probably drive me to do some more MAF calibration tuning.

What wideband do you use on the track? I ran the wideband sensors that could emulate the stock narrow band sensors and could screw into the front sensor bungs on my truck that 14point7 was selling a few years back, and reading their wideband output signal on two of my HPTuners Pro interface's analog inputs. One quit functioning properly after 6 months or less - I pulled them both and reinstalled the stock narrow bands as by that time I was as happy as I was going to be with the tune until I got around to installing my second-hand fuel pump voltage booster which I never did before deciding that engine's time had come. (Stock pump plus Vortech booster pump still dropping fuel pressure in that engine at around 5500 rpm and up at WOT and seeing up to about 11 pounds of boost. With help of the wideband sensors was able to compensate pretty well in the tune with the meth injection.)
14point7 started selling a different drop-in wideband sensor that could emulate the narrow band output with a better warranty about the time mine failed - that would be my current choice unless someone were to shed light for me on a better alternative.

I use a aem wideband in my car and my truck and have never had a problem with them, super easy to use. I used a LC1 in my firebird and it worked well but it was a pain in the *** to set up and required a recal all the time.

Since then have installed higher ratio roller-tipped rockers and descreened the MAF, which also necessitated a MAF recal.
