Hey everyone,

One of our customers just flashed his car with Mission Performance flash tune. He used the JB4 as well along with our turbo kit and TBI! He said he will get some runs on the weekend for the car. I attach some of his results on E35 and 21.5 psi of boost:

That power curve is so beautiful.

And that AFR is so nice...

With meth or without?

Hey thanks for sharing

What’s the graphs telling us I can read them very well.

Is that also using MP tune only or is it using JB4 for boost control also?

Bottom graph is with the stock catback, it is power and torque and AFR.

Top Graph is Just Power and torque (583 whp) straight piped from the d0wnp1pe.

It is using JB4 to control boost.

Nice. ~570whp with only 21.5 psi of boost and that AFR? Impressive.

[Mrpink]

Thanks,

So flash tune controlling AFR, timing and fuel, then JB4 doing boost?

Yes, I like the setup it has. Hopefully he will send more data soon including logs and Dragy Runs

Sort of like what a BEF might do, I suppose. 570whp with stock exhaust and limited bolt ons is nice.

I'm still blinking at that AFR - 1:15.8? It's really lean, unless I'm seeing the number wrong... the pics are low-res. . I suppose the meth helps, but I was hoping to see much lower AFRs given the cracked fuel cap...

Exactly what I was thinking. We are finally seeing what results can look like with the fueling uncapped. I'm very excited to see this.. Would love an AWD m240i, curious what that kind of setup would do in the 1/4 mile.

Can't read much on the pictures at that resolution. Can you also post raw JB4 logs?

12.8:1 really good AFR for this engine! I think the previous graphs were not clear.

Not my car but he said he will send them on the weekend when he has some time.

Agreed, the new pics make it clear. 12.8:1 is very much improved. Thanks.

Hi Juan ! I want to know the Diameter of your Down pipe and Exit Diameter of the Masterpower Turbo. Ca t less ** is illegal in Germany. We can install a HJS 300 cpsi ** but not ca t less. What about other Stages in planing ?

Hi Christian, the d0wnp1pe is a 5bolt outlet from the turbo which then connects to a 3” lower p1pe. We have enough space for a *** in there

100-200: 7.58 is that comparable with stage 1 m3/m4’s?
