Re: scanner results
cells stayed 15 - Normal
blm stayed 128 - Normal (a question - are you running a closed loop tune or an open loop tune? The BLM's will stay at 128 for two reasons, one being an open loop tune, and the other being the case where the BLM's in the high load cells are "reducing" fuel.)

836 6105
792 6408 - Recognizing that the data from the O2 sensors is not very accurate at the typical WOT A/F ratio, it appears that it may be leaning out over 5500rpm. Might want to check your fuel pressure at 6,400rpm/max load.
right o2s
792 6408
863 6380
890 5885 - still leaning out, but maybe not as much

39 5994 - depends what the progammer set it at. Normal for it to increase as RPM goes up.
no knock - good
MAP
4.84v 4345
4.72 5390
4.5 5995 - looks a bit low... about 92kPa. Means you are possibly losing 10kPa in the intake system.
4.56 6298 - minus 9kPa
4.64 6408 - minus 7kPa better, and roughly 2"Hg vacuum, which represents a reasonable loss. The higher you can keep the MAP, the more power it makes. Check the filter, see if it needs to be cleaned.
mat stayed 71 - good
IAc stayed 118 - normal. No, it should not be moving. It opens up as RPM increases, to a point, to prevent the engine from stalling if the throttle blades suddenly close.

i am going to buy a fuel pressure gauge because i was concerend with that very thing.
my intake system is new (moroso CAI and new 58mm tb)? What else could be causing the lose? bad sensor?
I hope to be making that amount if not more thats why im worried about my tune. i know the shorty headers are holding me back but.... i would like to think not this much
