I don't have experience with this issue, but what came to mind was this thread on here where they delayed the injector start time until after the exhaust valve closed to avoid putting raw fuel into the exhaust. Have you tried that to see if it cleaned up the AFR instability when running in MAF mode?
I have not tried that no. Not sure how I'd go about that on a 95 lt1 but I've had pretty good success switching over to sd in terms of drivability, after much tuning obviously. I am running a wideband as well as my factory o2s and they're reading pretty close so I don't know that raw fuel tainting was so much the issue as much as what happens to readings from the maf with big cams. I also don't have as much experience in tuning maf as I do sd but It was a terrible tune, worst mail order I've ever seen. I might mess with it more in the spring or when weather permits but it's started snowing here already
