Without a turbo or a better means of maximizing heat energy losses or the ability to utilize more internal energy of the fuel, I suspect that where or what you readings may be off a bit. Just a thought.

Its a 93 Del Sol thats about 2" lower then stock. Thats the only aero mod at this time.
I'm running two wide band sensors(PLX wide band with gauge and a Innovate LMA-1). Both are around 18" from the turbo. They both read the same all thru the rpm range.
I use the LMA-1 for tuning other cars and recently had it in a Honda B18 that would miss fire at 16:1 A/F at light load. So I was totaly surprized when the Del Sol would run this lean and still make great power. In fact it will pull a hill at 17:1 and not even slow down.
But get this at idle I can't go over a 15:1 A/F with out it starting to do the lean miss thing.?
