As long as Arrington doesn't actually touch the motor it might be OK. I had a supercharged 392 in my RT from them and it was complete crap. Don't get me started. Lost a lot of money on their junk
I had a good experience with them...I had a supercharger kit put on by them in my 2012 Challenger SRT8 (had the car trailered there from NY). I used it as a daily driver and it held up fine...no issues. This was done 3 years ago though, so I don't know if they have fallen off a bit recently. The only thing I will say is that when I went to put it back to stock (trade-in), I did not have all of my stock components in the box they gave me back, so I had to do some searching and luckily my shop had some laying around.

I'm pretty sure Arrow Racing and one other person can tune the ECM, but not for street applications, only track if Dodge approves it.
Getting back to the crate engine the factory ECM and tune would be fine for a street conversion hot rod, older mopar, etc , no the tuning is not available yet but in time. The simple conversion would use a 8 spd OEM trans or 6 spd manual, but if a NAG 1 or other is the choice a 6 spd ECM is used and a stand alone controller if using the NAG1 or 4L80, a TH400 or glide need nothing.
