I replaced my WB 02 sensor and wanted to try it out. WOT from 60mph almost instantly went to 100kpa. The Vararam picked up 2kpa from the dyno and I've never had more than 97kpa with any of my engines under any conditions with the stock MAF. More proof the 100mm makes a difference?
My tuner wants to go SD so I am going to sell it.....Hell it just showed up in the mail and I never even installed it.
SD is "cool" but the MAF's job is to optimize the tune based on current air density.
If you take away that tool the PCM will give you it's best guess without that valuable info.
Even in FL you will have more days than not, when performance will less than optimum. In fact it will be best at the moment the SD tune is done.
Car manufacturers do not throw unnecessary components into the controls scheme.

Is the tuner having trouble getting it to idle right?
