    How does that shift, is it firmer...?

    Check the high ends of the PT upshift/downshift tables, make sure the upshift MPH is greater than the downshift MPH...
    I edited this, see attached .tun file.

    The WOT shift on that felt pretty good but it chirped the tires which suprized me.

    Today I was taking off probably about 40-50% throttle and when it shifted to second it chirped, but I think it was becuase the tires hit a spot on the road with some pine straw or something on it.

    Something was wierd with that shift. It was like Right when it was shifting I let off, becuase I wasnt trying to go that fast but I needed to go through the shift to see how it was at WOT. So I let off right when it shifted or something.

    If it's chirping, you can increase the TR curves and/or reduce the pressure curves a little.

    Ok I just went out and took a run.

    I can say its getting better. Sometimes like when going up a hill the shift feels a little slow, but when downshifting from 30-35 then taking it all the way to redline the shift feels good and fast.

    And chirping is what I like I dont mind it I think its cool.

    Anyway it feels good but I think there is more in it, would the hard shift at WOT, that it could give, feel like the part throttle hard shift it gives now?

    Can I go more pressure on the downshift? Or is it not worth it?

    Another thing I like the non tow/haul part throttle shift.

    Its the kind of shift that dosent throw your head back and forth but it is soft, but really quick.
