Jb4 reviews?

[pj_singh1994]

like the title says, looking for any reviews from people who have had the jb4 on the trucks for a while now.

trying to pick what tune to go with. jb4 has always seemed simple on and off on my past bmws.

if anything, ill just go cobb but i have the jb4 app on my phone already so thought might as well look into it

I put one on my 2019 about three weeks ago.

It is a nice mild piggyback turner that is not crazy.

If you just want a little more top end, then go for it, but Cobb will give you more options.

I bought one because it supposedly isn't traceable by normal service dept. checks. No idea if it's true. I took mine off about 6 months ago, had to have some unrelated stuff done under warranty. Haven't put it back on because the dealer didn't fix one of the issues (seat heater). Have been waiting until then to mess with it.
If you search, there's a guy here that put one on and posted up some 1/4 mile and 0-60 times. The JB4 is legit.

I was wondering the same thing since I've always had BMWs with JB4. The Raptor JB4 isn't too impressive though compared to Cobb plus the price and capabilities compare when you talk Bluetooth on your phone vs accessport. I decided to look for a used cobb if there are any around.

I’ve had jb4 on past cars before. I was hoping to find out how everybody’s enjoying it and how it’s holding up

What map are you running? Octane fuel?

If you're looking for a piggyback setup and not a full ECU tune, Burger JB4 is hands down the best out there.

Be glad to answer any more questions or help get you setup!

F-150 EcoBoost/Raptor JB4

What map are you running? Octane fuel?

I’m running map 2

92 octane, best I get in the hills on Tn

Good all around improvement in power? I gather you would need 93 octane or E85 mix/Octane booster to take advantage of Map 5 from what I have learned.

I feel it most at full throttle.

Yes you would need a little more octane to take advantage of the other maps.


I really did it to say I have 400 hp to the wheels.
