Damnit now I have to void my warranty because I want one LOL

It's an excellent tuner with a lot of safety built into it to keep you from damaging anything. I'm kinda stubborn and don't follow directions and have changed settings that I probably shouldn't; each time, it simply reverted to stock map to keep me from blowing the engine up. I also never remove it when I go in for oil changes and my service dept has never said anything about it.

I say that to say, go for it, you won't regret it. 👍

interesting. It is on my list of mods now after the catch can. I only have 300 miles on my car and two free oil changes so I may wait until that happens. After that I will do all my own maintenance as I have done in the past. It looks plug n play. I am assuming it is. I do like the built in fail-safes. I cant remember if I read this or not but does it have a built in turbo timer?

900 miles in and loving my JB4 on Map 2, so smooth compared to my Q60 RS and love the gearbox in comparison.....waited until 600 miles then I couldn't wait anymore....

do it is all I can say...if you dont like it take it off and it won't take 10 mins to sell but you won't want to just CAIs and I'm on 4.4s and 12.4s with not great starts....

I was under the understanding that if the JB4 is removed and everything is put back to stock then you warranty would not be in jeopardy.

Correct, if you take your car to the dealership you just have to remove it an they will never know you had it on the car..

Looks like a JB4 is in my future.

Yes you can run your stinger stock with JB4 & with plugs changed.

and what type of gains will I get over stock ?

Your gains will be around 35 HP but make sure you have a Oil Catch Can on the PCV side of the engine or you will have a crap load of blowby going into your Manifold & on top of the valves... I'm attaching a picture to show you what I mean..
