Just added a drop in K&N. Have a Super Chip on stock. Started to consume more fuel than before; loss about 3.5 mpg. I've heard you sometimes have to reset the computer to get it to adjust to new mods. Am I correct.

 

disconnect battery's for 10-15 min maybe?..... works on the jeep, why not the dodge?

 

I noticed a decrease in mpg recently. I took truck back to stock & re-flashed Stuper-Chip Performance setting & my mpg's are even better than before, I broke 20 for the first time combined city & hwy.
