ESS vs. JB4 - Which way should I go?
I am looking for opinions, experiences, tips, etc here. A full review of both products on one thread would be great. I am looking to purchase one of these tuning products soon, but without more information and real world experience I am a bit stumped as to which product would be best.
My major concerns / interests are:
1: Dealer detectable? Do I have to remove the JB4 before a dealer service? Do I have to revert to the stock code if using the ESS?
2: Ease of use? The ESS system seems more straightforward and easy to use, but also seems to offer less options than JB4. Do I need all the functionality of JB4?
I would really like to hear existing customers of both ESS and JB4 contribute their experiences here.
Thanks
