I’m on 37s and regeared to 4.88 and I can’t get better then ~13.xx mpg’s. 19 mpgs would be a dream. But then again I didn’t buy a jeep expected it to be a gas saver lol.
I brought a club (steering wheel lock) last week since car theft is back on the rise in my area. I also enabled the hood alarm via my Tazer and also added a kill switch. As a friend of mine stated, they don’t want attention, or having to work for it when there are other cars they can go after.
I have the Banks and love it. Only downside is it has to stay plugged into the obd2 port and you should unplug it before any service visit at your dealership. But absolutely recommend it.
Just get a K&N filter and call it a day. I feel like it helped allow the engine breathe easier (I can feel a difference) and helped with mpg. Also dealer cant complain or void warranty if they want to difficult when dealing with a warranty issue.
