A tune can not cause a creek. Has to be some thing in the suspension or mounting bushings. I had a 96 Dodge caravan with the same problem. they looked for it for ever. Finally found it it was of the the bushings that held the body to the frame. They had to replace the bushing and the bolt and re ...

I'm calling 60' times ranging from 1.9Xs to 2.4Xs

what did it run stock? Do you have any trap speeds or 60ft times?

You had a 1.6s discrepancy between different tunes? Sounds like something else went wrong... did it start raining for the other runs? LOL!

They've had it for almost 2 weeks now and have (so they say) literally replaced, remounted, retorque, and relubed every piece of the rear suspension. He even lubed the bushings for the exhaust hangers LOL!

They're going to have a Chrysler field engineer come look at it next because they've already ...

I'm worrying myself into a tizzy here... I took my 2009 Charger SRT8 into the dealership because there was a 'creak' in the rear somewhere whenever I accelerated from a stop or from idle speed.

They've had it for a week and have replaced the entire rear suspension system and still can't find the ...

Hi guys, I'm sorry, I still don't fully understand what the MPG Booster Tune is. I have a U7135 for my 2009 Charger SRT8 running 9r29. Is it simply so I can run 87 octane gas? I thought I could do that anyway with a stock car? I thought if I put 87 into a stock car that the PCM would adjust? Or ...

I'm going to voice a concern that has almost caused me to wreck my 09 LX... I hate how the canned DS tunes loosen up the stock traction control tolerances, and there's no option to put it back to stock (without removing the entire tune from the car). The first time I drove with a tune tune in the ...

i know the tunes also loosen up the traction control and shift firmness vs the stock tunes. however, currently (i think) they are not options and are completely embedded into the DS tune file. how about also making those two things "slider options" as well, similar to the throttle boost? where the ...

I did that. 9r28 is currently in the predator and it's still asking me to downgrade

2009 Charger SRT8, U7135 Predator tool.

I had the 93CAI tune with raised shift points and raised rev limiter in the car when I had to take it to the dealership for service. They took the liberty of reflashing the PCM for me :normal: . Now the tool says that my current CALID is 68004302AF and I need ...

EDIT:

Disreguard the above I found the answer in another thread. I'm assuming that the support for 68052005AD will be out in the near future so I can go back to "normal"? :)

2010 Challenger R/T Auto
What thread did you find the "downgrade" details in? I'm on 2AF CALID and it's telling me to ...

bump? What are my options if I don't want to downgrade? Wait until the next tune release comes out?

Thanks!

Hi, thanks for the response. What are my options if I don't want to downgrade? Do I have to wait until the next tune release comes out? (9r29?)

Sorry guys, I have seen a bunch of posts about CALID's ending in "AD" but none ending in AF. I get the "Your calibration ID is 68004302AF and you need to downgrade to 68004302AD." message when I plug in the predator. My PCM was reflashed about 2 weeks ago (pretty recent). I don't know a lot about ...
