Yup,
I’ve NEVER had a reflash that has done much of anything with performance except make it worse in the name of emissions/economy lolOnce you have tuned ECU, you do not need updates. Tune optimizes your engine operation, if tune is updated - you can get free tune update over email and load it on to your Jeep.
Let dealer load pointless updates on the stock ECU.
