Ok so I have been considering getting my 97 XJ's computer flashed because I have never done it before and I heard its a good idea to get it flashed every few years just to clean it up like you would a PC. Anyone ever done this? What happened after you had it done? My concern is I fought a Check Egine Light issue for over a year and I tried many different things to fix it frequently clearing the codes and having it come on and off alot logging in the issues in the computers memory. Now I used to get 17 MPG on the highway doin 70 mph before the whole CEL issue happened and nothing on the jeep has really changed other than I changed out the muffler from a gibson to a flowmaster 50 series because I liked the sound of the 50 series better and I added 4 lights to the front of my Kargomaster roof rack. Now I get at best 13-13.5 mpg on the highway doing 70 mph. That to me seems like a considerably drastic loss in mpg and I would be surprised if my changing of the muffler and adding lights would cause that much loss in gas mileage I mean I expected a little loss from the lights due to wind drag but not THAT much. Anyway I'm just looking to get an idea of what would happen if I flashed the computer.
