Are you guys feeling a better torque at the low speeds 2K and below with the OTS maps compared to stock? Fill me in please.
I have to think Toyota made cams go to lock pin at 800rpm to avoid any chance of pre-ignition by lowering the effective compression ratio.

Did you add KCA to base timing? Because comparing Base Timing itself to Stock will lead you down the garden path.
You can get some files with flat KCA from one of my threads so you can compare total timing all you want. You'll find the openflash tunes have MUCH less timing at high rpm / low load.
Or Kodename probably has a spreadsheet for it along with everything else.
