Dyno results: JB4 with backend on E30

We set this car up to run E30 and had some pretty good results.
Graph in video shows JB4 map 2 vs our custom back end running map 6.

Not bad at all (mustang dyno too). A little clarification? Map 2 run was with no back end flash and e30?

Map 2 was run with no back end flash on 93 octane.

To further clarify this e30 backend was setup to run 93 with meth on map 0 16psi or e30 on map 6 19psi.

Here is a 93/meth pull on map 0 with the back end vs. jb4 map 2 on 93 oct with stock flash.

What other mods were on the car?

Also, just a critique of your video, that intro was way too long and the music played too much over the car on the dyno imo. I don't mean any offense, just a suggestion.

In the 1st graph you lose hp&tq until 3850 rpms exactly, but in the 2nd you don't.
Is it me or is it kinda weird?

Thanks for the critique! I'll take that into consideration on the next vid I put out. Luckily for me I'm a professional engine tuner and not a movie producer
The car has: Wagner IC, Cobb high flow Dp's, Spec stg 3 clutch and lwfw, Walbro 255 inline, and the BMS meth kit.

That is just me rolling into it a little easier on that pull.
