Dont let them tell you that third party tuning i not available. My 13 ripped jk had serious tuning issues when installed in august of 2014 wouldnt rev above 5k rpm with out falling on its face and so on. A local and reputable shop near me (i live on long island new york). The shops name is chris miller racing out of deer park long island new york. He brought my jeep in put it on the dyno first pass from ripps tune made 250 wheel. After 5 passes on the dyno and fine tuning my ecu thru the diablo i made 344 on 8psi running conservatively. My truck still is a little hesitant to go above 2500rpm when cold but once my scangauge gauge reads about 150 coolant temp it will let me open it up nut you should always let the engine warm up prioir to romping on it
