Looking for advice on which ecu to use. I am currently running a factory ECU to run my 5.7 hemi. I really need to loose the DBW and gain some tuning capabilities. I am using a Hotwire wiring harness and plan to just pin out to whatever ECU I use. The two I am looking at are the MS3 Gold Box and the MS3 Pro. Anyone out there using either? Pros and cons?
