$6E failed emissions with 128 BLM?
I failed Oregon emission testing with over 600 HC's. I used Data Master TTS to adjust the idle BLM's to a near perfect 128 BLM. The remaining VE Table was 128 + /- 3. I needed to increase a couple cells in the MAF #1 Table by 1.00 ~ 1.22 Grams per Second to get the BLM from 150 or so down to 128.

Any tips, suggestions, or comments are welcomed!

What was the 02% reading. If HC and 02 are high, there is a good chance the engine is misfiring.

HC - 827 ... Limit 220
CO% - 1.72% ... Limit 1.0 %
