Default Fuel economy with JB4? - 08-18-2018, 09:52 AM

Hey guys, just curious, but for those who have had there JB4's installed for a while and can drive it normally, are you guys seeing better or worse fuel economy?

LoL, for most people when first intalling the JB1 or JB4 your gas mileage sucks due to all the new power...
