Advantage of running the 1Bar OS over running the standard OS without a maf

[LSGUNSS]

Just like the title states. I have a 2000 S10 with a 5.3 H/C/I/E that I am running without a MAF and want to know if or what the Advantage of running the 1Bar OS.

There's a detailed write-up by Bill or it might even be in the stickies or Help file, but main reason I use the Enhanced OS for MAFless cars is the retaining of dual spark tables. If you fail the MAF on a std OS, the PCM immediately reverts to Low Octane (and Secondary VE table with half resolution on some earlier OS). There are a couple of other benefits, but the that's the primary reason for me.

RTT is the biggest reason. I normally don't care much about the dual spark table stuff because most of the setups I tune is 93+ octane anyhow so the low octane is just a copy of high octane. If you have a pre-00 OS it will do away with the half resolution secondary VE table which is what will be used on the stock OS.
