Anyone Piggback the JB4 with Ford Racing Tune??

Has anyone piggybacked the jb4 tune with the Ford racing tune? The Ford tune AFR at WOT is 10.2 which is pretty fat still. Just wondered if the low boost add from the JB4 works with it??

That’s a terrible idea

From what the site says stage 1 adds 3 psi

Folks have done it apparently without issue. I may try it and take a few logs since I still have my JB4

If you do let me know how it looks.

I have a JB4 piggybacked on FP tune on my 2.3 Bronco. Definitely makes power! I also have water/meth injection and colder plugs. Haven't gotten that far on my RR yet...gonna try an intercooler 1st

I had done a stacked JB4 on an APR tune on my '19 A6 for a short while and it worked pretty well (I know, different situation entirely). If you use map 6, you can tweak everything on the JB4 and add incremental boost through the Rev range. I used it it run E30 on a 93 octane tune. The only reason I stopped doing it was because Audi uses a torque target and will cut boost once it hits that target, so I stopped seeing any gains even though the engine had a lot more in it
