Sold my truck so I'm selling the Predator (U7193 version 9r11). Works great; unlocked of course.

$185 shipped via UPS or FedEx with the USB cable and AC cord.

Are there any plans to develop this tune for older models (U7193)?

I ran a data log yesterday and the program recommended a -6% injector slope setting (avg LTFTs were ~5.7). The air temps were in the low-mid 20s. I thought I read in the forums somewhere that with lower temps, it is best to adjust the injector slope to get LTFTs in the 2-3 range that way, when ...

If you modify the tune using the 87 Octane tune (adjusting injector slope), do you have accomplish another live data run and adjust fuel trims again if you switch to the 93 Octane tune?
