I realized that $42-1227747-V5.2.adx and $42-1227747-V5.9.3.xdf are the files to use. These files are loaded with parameter information. THANK YOU to whoever has written and added all that info. I disabled EGR, with the patch provided, since I removed EGR. I disabled Air Diverter. I unchecked Pass EGR. I unchecked Code 32 so I don't get a CEL. I changed stoich from 14.7 to 14.13 because of E10 fuel. I changed Max Spark Allowed from 41.84 to 36. My 5.7L is not too far from stock. 9.4-1 CR, Melling MTC-1 Camshaft, Shorty header w 2 1/2" out the back. I think I am just going to kick up the fuel pressure a few pounds, add a little BPW, fire it up and tune from there. Antone see any problems with me doing this?
