Scrambler Booster Plug On 2015 Scrambler

Have been getting really pissed off with the way the throttle responds at low speeds especially on roundabouts! I came across the booster plug on the internet and thought it looks like an easy fix so I bought one. It arrived the next day, took 10 mins to fit and very easy. I went for a quick spin and round a couple of roundabouts multiple times and its definitely improved the low rev on/off feeling. It now feels smoother when increasing/decreasing the power, especially on roundabouts! I will test further later this week and I do intend to fix this problem properly maybe with TTP tune up kit, but for now its feeling better.
Has anyone done the TTP tune up? Which tune kit did you go for?
