Just tuned up both the Ram and Dakota last weekend. Installed E3 plugs in both, seen the pro's and con's, plus the Powerblock TV show,was kind of impressed by that.Installed Summit racing 8mm wires in both. Accel coil and Spectre CAI in the Ram. Accel cap and rotor in the Dakota. Bought Superchips flashpaq, tried it in Dakota before tune up. Loved it!! Major difference. Wasn't happy with low end performance in Ram always been sluggish on take off, even after tune up. Didn't come on until around 2,500-3,000 rpm's. Returned Dakota to stock and installed Superchips on Ram.Wow, what a difference. Can see why everyone recommends them.Low ends a whole lot better. Can now give a Hemi a run for it's money, may not beat them, but will make them earn it! Just ordered a Superchips for the Dakota.
