Im looking to get a custom tune for my 07 5.7 Hemi Ram. It is my understanding that SCT and Diablo are my two options. My question, what are the tuning parameters of these units?
thanks for any and all help

 

I would go with a Diablo unit, as most shops that provide custom tuning on the Dodge platform use their CMR software.

As far as parameters, the inTune from Diablo has a few options that can be adjusted without getting a custom tune. I cant remember what they are off the top of my head though....

 

SCT wont work on the 07 I have an 07...lol Diablo all the way.

 

go with diablo. johan at diablo can help if you can reach him. my stock 2007 chrysler 300c made 330 horse and 375ftlbs. torque with some afr and 26degrees max timing on 93 octane. 12.5 afr btw. i baselined with a 93cai tune and went from there. do some road data logging for short term and long term knock retard. add fuel were needed. then get it on a dyno. go for 12.5 afr. maybe try adding 1degree timing down low and one up top to see if it hurts or helps power. good luck.
