well, my bud has a 2012 auto with 3.21, on 315/75R17 (approx. 35") MTZ. He drove his jk for about 30 000km with this setup before getting a AEV procal module. And then he corrected his speedo and shift points with the procal, and he saw a good difference on acceleration and he finally was able to run the overdrive on the highway, which he can't before the reprograming.
to answer your question, no it won't be noticeable imo, if it was 500 yes it would, but not for 120. 34" tires and a procal and you'll be good for light offroading.

Finally got the lift and tires. I haven't noticed much loss in power. My rpms are only slightly higher as compared to the same speed with the stock tires. Over drive works fine on the highway. I lost about .5-1 mile per gallon on the highway. The tires are very quiet around town, at about 75-80 mph there is a hum, but not too bad. As for the aev lift kit, it is definitely "stiffer", drives more like a truck now, but that's ok. I can take turns much faster than with the stock suspension, it really sticks to the road. Overall I gained almost 4". I love the way it looks and am very happy with this combo. Can't wait to get it odd road.
