I never noticed that problem, but I did have an issue with a serious lag during the 2-3 and 3-4 shifts under heavy throttle. Those are now almost gone.
After over 1K miles on the chip, I'm happy with what I got for the $. My jeep is quicker (not faster) while gas mileage is about the same. ECO mode still kicks in when it should, and I find that is what makes more difference than anything else in my MPG numbers. One other nice note is that my exhaust now announces itself under WOT. Before the stock exhaust was pretty tame for a supposedly 360 hp V8. Now it's got a nice rumble when you step on it.
