As an FYI, I email diablo's tech support about the 87 octane tune. They were very general in response and basically said that they don't support 87 octane with their cookie cutter load and that a 120 dollar (not including the 35 dollars kit for the pc) custom tune would be needed to use 87 octane.
I guess maybe I can ask my questions here and get better answers.
1. I want to use the tuner to improve my automatic transmission characteristics. This should not require better gas. Based off the screen shots, you can adjust shift firmness. What is the advantage to making it firmer as opposed to looser? What are the disadvantages.
2. Has anyone had experience with the MicroTuner AND the Diablosport Predator? I know the Microtuner has some built in tunes for 87 and higher gas. I just don't know if you can get good custom tunes - one day I'll have a SC.
3. Has anyone used the Diablosport Predator higher octane tune, running 87 octane in a Mustang? I don't really want to pay 120 for a custom tune until I have some more stuff on my car.
Maybe others have the same questions, so hopefully this will be a useful thread.
Take care ya'll, and thanks for the previous posts and any future.
