Great write up J . The JB4 certainly filled the void for Me it’s the best tunning box/system I have used and I’ve tried a lot with very mixed results.
Jon R306
Many thanks, yeah I agree it does fill the void. Gives flexibility should you want to progress forwards, and allows you to sell it should you be selling up, or don't fancy it anymore. I am getting the itch for more but we'll see what happens
