Because what I see in data log is it is within the factory Narrow Band O2 sensor boundries for correction. Actually running a little lean at high RPM, but within correction boundaries.
There's some differences in 92 to 93 LT1 XDF for modifying the chip/bin. I just looked at the 92 and there's not much there? 93 on the other hand has had a lot of work done to it.
There are also 2 differant ADX files listed for 92-93 but notes seem to indicate they both start with ALDL 172.ds file so some things may need to change. But we do have a worked on $DA3 ADX data log file that would be a better start, what files are you using?
Finding out if the errors are correct in files would be the first thing, no reason to data log and try to tune with errors set. But I don't know what is accurate for your 92 LT1?
There's a lot of work that goes into making these files and not many Corvette guys have done the work or if they did not shared back. Here's a couple files I've worked on with others that may help you get going?
