I'm thinking that the high velocity air in the small air boxes we use is actually cooling the intake air to a point that the ECM is throwing in extra fuel when not needed due to the inaccurate IAT reading throwing the afr off and since there is no O2 sensor feeding info to the ecm it doesn't know it's over fueling.

It would be enriching the AFR across the board. Yes similar to a choke being partially on.

well I will play around with it at the dunes a bit and I got the front shocks re-valved so i'm hoping this is the last time for that as well. it's always fun and as long as I have a smooth ride and good weather with good folks it's all good lol  this is an irritating problem though and like I said with each part or mod it has gotten better so none the less it all needed to be done. the nice thing about the bazzaz is you can see what does work and what doesn't with the logger and fuel map. it is a nice tool to have for sure. It is not building maps based on each gear but rather has a fifth gear map applied for all gears, it's either that or a trd inline with the tps which I have one of those too. this issue was there before the flash though so it wasn't that.

I wonder what the atmospheric pressure sensor could do to it? I did not check that one and it is mounted in my electrical box.  I have also wondered if the computer could have a something left in it from a previous flash but enemy say when he flash's it that it automatically goes back to stock before you can reflash.

Yes ,it is important that it function correctly. Why is it in the electrical box?

easy location and it fit lol    i drilled a hole through the box's on all the other rails sand let the snorkle part stick out on those but didn't think it would be a big deal on this one, figured it would read pressure in the box or out since the box has larger holes in the bottom for ventilation.

If that box,when the buggy is traveling or even sitting still, sees anything other than a correct atmos air pressure it will fubar everything. Is there a possibility that the box is pressurizing with a high pressure area or by wind blowing into it? If it were me it would be in open air only.

I mounted atmospheric pressure sensor in elec box, but drilled hole and sensor is outside.  I could see the box pressure being off, like ram air? 

Drill a hole and stick it thru, bam easy.  Zip tie IAT sensor out of airbox, duct tape hole for test.  See if cows run faster on this pass.  ;D

well the problem has always been from idle to wot but most noticeable in midrange and temps outside have never made a change either but the box is enclosed except for the 1.5" holes the wires come through but the electrical does put off some good heat in there!
