What do I need to (rich-lean) raise or retard?
unfortunately where I live there is no good Mopar tuning
another question is will a Mopar TCM (for 2006-2010) work with my 2011 challenger? they have exactly the same tranny but is there anything different i should know about? ( I want it to disable the obnoxious auto upshifting!!)
Thank you in advance.
