I still dont under stand why you guys are messing with 'canned' tunes still. when i installed my ripp kit my jk ran decent for a 'canned' but didnt feel like all the power was there. I payed a local tuner to do dyno pulls and custom tune the ecu for optimal air fuel and timing that way i made 344 whp on 8lbs of boost and im still on a safe tune. You guys keep complaining that the tunes are a hit and miss go get a custom tune from a local reputable tuner. It will save alot of time and frustration dealing with your truck running like crap. One thing you have to realize is not every jeep is the same when tuned different sea levels different engine loads auto vs manual gears tires they can only tune one jeep save the tune then send it out for there customers. Some of your trucks are different and should be specifically tuned for your vehicle and setup
