Burger JB4 tuning available now

[drburns]

One thing to add about the DV+ spring as a potential issue is there are some guys running it with the spring and JB4 w/o any issues, and a couple using stock bov with the same issues I have.

Be careful when back the hardware out... the aluminum on the mishimoto inter cooler pipe is really soft! After 3-4 installs of stock vs dv+ with/without piston I stripped out one of the threads.

wound up re tapping and adding steel threads back in on all 3

I haven't looked at these in person so this might be a stupid question, but does it look like it's possible to install threaded studs instead of bolts?

I don’t see why not. I think the depth is almost 1/2”.

I figure yes... I just went the other way because of the hardware I had on hand.

The only trick of doing it with studs would be the length required. The pipe is actually two pieces... one is the main pipe and the other is piece for the recirculation port back to the turbo

So I pulled the spring out of the DV+ and only got one hesitation on map 2. The Jeep also felt a little more sluggish but I’m not sure if that was from the spring being removed or from the hot, humid weather (more likely).

Would I be able to use a OBD2 splitter so I can add this and keep my Tazer? Any issue with functionality?

Doesn’t interfere with Tazer mini. Only the JL

Yes, you can use a splitter, I do so with an "Automatic" OBD module to send locations, etc.

Or if don't own a Taser yet the Mini/Lite use the secure gateway plug and not an interference.

Hesitation and complete power loss can be a boost leak.

It only occurs from a standing start with full throttle on the 1-2 shift, sometimes 2-3 shift. Otherwise it runs fine. If I roll into the throttle it’s fine, even on map 2. I’m not sure if the Jeep is like other cars where the tune is torque limit based and it’s hitting that limit too fast, or what.

I had a Mitsubishi evo IX. I remember I would have intermittent hesitation when given full or part throttle. Till one day the intercooler hose blew off a coupling because it wasn't tight enough from the factory. The pressure from boost builds the hoses expand and the leak which wouldn't normally show itself will.

Interesting. Easy enough to check for it, although all the log files show it’s making and holding full boost.

I hope it helps!

I’ve heard they have a stellar reputation.

I’ve attached their dyno overlays. Impressive.

Burger is essentially a big name in the Bimmer world, so they're definitely solid

I'm seriously considering purchasing the JB4 tuner. Is this the best option out on the market right now? I've checked out a bunch of results with other makes and models (as well as the Jeep 2.0t) and am impressed. Thoughts?
