GTStanger, make sure you control as many variables as you can for your expirement. Do as many ABABABABABABA's as you can to average out the variables. No doubt that a few of the A's and B's will range out but you just want some consistancy. If it's totally random, then you can't claim any benefit. It's tough testing, that's why more people don't do it. I did some aero testing once, it took a long time and the results were not conclusive, so it felt like wasted time. You gotta be pretty serious about ecomodding to do a lot of expirements. I just take what's proven and apply it.
I have a MAF system and have observed what appears to be a benefit, although I don't care to test for it, I keep it on for it's preceved benefits.
LOD is what I use these days to judge fuel economy potential of mods
I'm looking to raise my lOD
