Different car makes and years have different fuel management systems...resulting in differing results?
I'd have to do some dreaded A-B-A testing to prove anything though.

It would be interesting to see if you had different results than Sentra-SE-R, if you indeed have the MAF too. You might avoid an ABA test if you look closely at the systems in his car and compare them to yours... maybe there is enough similarity to convince you that his results will likely apply to you too--and so no testing needed. Also, one guy was suggesting I try a Cold Air Intake, which the ricers and racers love to buy to boost horsepower, but which might also boost FE if different driving techniques are applied. I have attempted several tests now and the results nearly always surprise me. And yup, I fully dread the time needed to test anything just now. So I am doing relatively uncontroverisal and not so creative mods at the moment: airdam, rear undertray, and wheel skirts.
