Thank you very much. That's very helpful. I'll download the instructions, also.

Thanks again!

I know I'll catch a lot of flak for this, but how do I run a log on my vehicle. All I know how to do is put in the Predator tune, and restore the original. I've read the posts that mention posting the log from there vehicle, and I was just wondering how to run a log. Also, what will I learn from ...

I would like to hear an answer to Kevin's question, also. Thanks.

Bottom line after all this is simple. I have the test installed and like it, so I'm keeping it. You should do the same. I won't have to suffer through the placebo effects or the nefarious secret tunes. lol

Ditto!

That's interesting. So when I restore it, it will be a different calid than the AF the dealer flashed or the AE it came with? Is that right? Sorry, but, as you can tell, I'm not a computer genius.

Last update. I did it. I don't know how, but I did it. I did a calibration update from the downloader. I then let it upgrade my vehicle, and then it installed the 21c program. I have no idea what calid my "original" is. I guess I'll find out when I restore it to bring it in for service. I took a ...

A little update. I decided to relent, and let the Predator downgrade to the AE calid. When I did, it tells me my car needs an update to the AA calid. What is going on??? Even when I do it your way, it still won't work. What do I do now?

I took my car out of storage, took my Predator out of the closet, downloaded the 9r21c program and was looking forward to finally being able to tune my Challenger R/T as promised. WRONG! It still does not support 05187899AF. I understand why you spend your time making it compatible with the 2010's ...

Does the 9r21c support the 05187899AF calid in 09 Challenger R/T 6 speed? I've been waiting awhile.

That sounds more realistic. Thank you.

That should say expectations.

Does anyone know what HP rating I can expect? I have the 09 Challenger RT 5.7 Hemi, 6 speed. I have installed the K&N Air Charger Intake, MoPar catback, and will eventually install the Predator 91 oct cai performance tune. I know K&N promises 21.09 HP at the rear wheels, but I find that hard to ...

I was able to access that and it was interesting. My vehicle doesn't seem to be affected, yet they reflashed it anyway. I'm going to check with the dealer to see why they did it. Thanks for your help!

I tried accessing that when you first posted it, and again now, and it says internet explorer can't open the site. I'll keep trying and thank you.
