OK from what I've gathered SHIFT firmness is not available on 6.1l models..why is this? :-\

Ok, I now have my calibration info # it is 6800438AD, my predator was orignally programmed for a 300c SRT-8, and when I got the Challenger SRT-8 I upgraded it to 9r27, however I am missing lots of parameters such as shift firmness, fan settings, etc, in quick adjust I only have 4..
Shift point
Axle ...

PCM flash they might not even charge you, it's a 5 min job. The only issue I'm thinking of, is if you still have warranty, I've heard dealers will turn down\take away your warranty over Predator tunes.

Easy...

Go to Performance Tunes
You will have to accept, then turn key on, continue
Then to Quick Adjust
Then to Transmission and then you'll see it.

Yeah mine doesn't have that option :-\

what is your calibration ID?

I'll have to find that out next time I go out, what would that change? I originally used this on a 300c SRT-8 (2008) and reflashed it to 9r27 for the Challenger...does the 91 octane perf tune change firm shiftness? if it does then that would explain the kick I get now ...

No, it is in the Quick Adjust menu, you dont want tomodify the stock tune.
Could you show me where shift firmness is then, because I can't find it I just went down to plug it in and check, I see axle, shift points, dyno, and tire size...that's all under quick adjust...and under shift points it's ...

I did some research and apparently it's under "stock tune modify" so I don't know if that even effects it if you're using a diablo tune :-\

All problems are fixed for now BUT my 09 Challenger RT is getting terrible gas milage. Example: before the 93 CAI tune 20 mpg in town NOW with the 93CAI tune 14.1mpg. I have a catch can, resinator delete with deltaflow Flowmasters, and of cource a CAI. Can I tune anything up or down to try to help ...

No harm to the tranny, just allowing the engine to hold timing between gears.
Does it do that in autostick to? Because I feel it a lot in autostick as well.

Also, can you even modify the tunes? I was going through on my Predator and all I see is modify stock tune...I was wanting to modify the 91 ...

Mine kicks like a muel going from 1st to 2nd with the 6.1l...so I guess so? What exactly is "shift firmness"? I could be mistaking it, it's very on time...just rough.

Just wondering if this is normal, with the 91 Octane perf tune (stock), if I floor it when it shifts into 2nd gear the car "nudges" you a good bit, like it's doing a hard shift...checked it, doesn't do this on the stock tune...is this what makes you able to "bark" the tires going from 1st to 2nd?
