im pretty sure when you install a chip they are locked to your vin number unless you unlock it so people cant steal it or something

 

This. They get VIN locked.

 

anyone else have any input

 

I drive a 97 1500 ext cab 5.9 with about 145xxx on it iv got 32 11.5 15 i bought a cold air intake i get about a mile per gallon better bought a hypertech tuner didnt change im getting 8 mpg i would really be happy with 13 i would love to get that im looking at a electric fan and that should help 2 -3 mpg but if your worried about gas money the 2nd generation is not for you i would look for a hemi if your into dodge

 

The hemis aren't that incredible on gas either. If you want more MPGs, get a moped or at least a small 5 speed car.

Our 04 durango gets about 12, or 14 if my moms driving. lol
