Anyone found a chip for the 5.7 hemi that actually increases fuel mileage enough to pay for itself? Someone told me they were out there but I want to hear it from someone that actually has one.
Large chip of wood under the far right pedal.
Sorry had to, I have a few people that have tried a lot of different tuners and haven't come up with any that really improve mileage, so sorry no help here.....goodluck
