    i got my diablosport in about two weeks ago or so< maybe 2 1/2. and as soon as i installed it and took it for the first spin, right away i noticed the firmness in the shifts. well a few buddies of mine said to give it a few miles for the truck to learn the new program. well its been a few hundred mile (like 250-300) and its shifting all good, except going into 2nd gear. all the other gears it shifts like a dream, just not going into 2nd. its not like really hard and doesnt do it all the time, but most of the time. sometime harder and sometime softer, sometime perfect. but usually its just kinda like a medium firmest, noticeable. anyone have any idea wats goin on?

    OK, if you go into the adjustable parameters on the Predator you can lower the part throttle line pressure settings to your liking, then reinstall the tune.
    Let me know if you need anything.
