I believe the P5155177 is for SRT's only.
Yes
P5515177 or 179 6.1
P5515224 or 225 5.7

Got the impression from the guy at Mopar Performance that the 5.7 one wouldn't raise the shiftpoints. Can't believe that though, maybe I didn't understand him right

Mopar Performance 1-888-528-4364

I did some looking and found a few guys that had talked to some mopar reps that said the P5515177 was made for the R/T's and SRTs only 09+....

Man, I would love to hear this confirmed by a 5.7 owner who installed one and tested out that claim.

Most results like myself were on 2005-2007 cars, the 2009 R/T's are still a mystery.
The P5515177 will definatley work on a 09 6.1 and it worked on my 06 Charger R/T but if it will work on a 09 5.7 R/T is still unknown.

The 5155224 for the 5.7 I don't even know if its available both of these are made to work with the 05-09 computers where the earlier model MTCM only worked till about 07-08

If I was assured the xxxx177 would work on a 2010 5.7, I'd buy one. But I have not read a 5.7 owner use the SRT TCM.

It's kind of like with the Predator, it has no options for a 2010 tranny, cept' firmer shifts.

Here is the sheet that comes with the 5155177, which on the TCM says PP5155179AA

I have seen this as well.... One of the things that made me think it would work, but then no one has used it...I am still hoping that Hptuners will get done and then it will be no problem!

rofl, overstatement of the year....

You do realize they have not even talked about NGC4, nor do they have any immediate plans for TCM support...??

Well I installed P5155224 in my 2010 RT Classic and all I had to do was change the gear ratio to 3.06 and wow what a difference.

Great mod!

Previous years for the 5.7 was 2.87 or 2.83 gears, can't remember off the top of my head. Anyways just used the intune and adjusted and I was good to go.

Once I installed TCM P5155224 it defaulted to the 2.86 gears so I had to adjust it back to 3.06 and it works great.
