Dyno was mainline Dyno (Lowest reading Dyno, lower the mustang) I did 555whp on 22psi Map 2.

The Jb4 and backend ecu flash works by adjusting to all boost parameters and utilizing the jb4 and BCM as a boost controller.

For comparison on Map 2 Jb4 and BCM without Backend flash I did 620whp on a dynojet.


The video above is at 24psi. After speaking to my tuner I can do 25psi on premium 93 and 27-28psi on race gas (E85- Ms109)

So far no issues with clutch, the thing pulls so damn hard as you can see on video.

Who needs downpipes and that annoying flutter when you can do this and have the power without the annoyance!

Tuner is Info@EnzoPerformance

I will be dynoying it on same Dyno (dynojet) that I did with previous JB4 only and see result. Shooting for 650-670whp.

They have done my last car (world record 550xi) FBO and tune only I did 11.5.
