I have done much to my 1998 GTP in the way of tuning, but have never tuned anything else. I just bought a 2007 Dodge Dakota and wanted to start tweaking, but I'm not sure there is anything to gain on a stock setup. I've looked on here and on other sites, but have not read anything about tuning these motors. I don't see any problems while scanning (knock retard is always 0 and fuel trims are damn near perfect). It seems a little weak and gas mileage is low, so I was going to start by playing with timing first.
Has anyone done anything to a 4.7 in the way of tuning? If not, I'll post what I do but like I said, this is completely stock.
