I am running the newest JB4 Stage 3 with
The G5 box. I have owned several turbocharged
cars, this is my 2nd German turbocharged car,
out of 5. But carrying on has anyone taken a
closer look on what dyno meter that the cars
have been strapped on, JB4 was on a dynojet
and Cobb was on a Mustang load bearing dyno.

This saying looks like the COBB makes more power
regardless of it spiking at a higher boost pressure.
Yes I agree that currently the JB4 makes or seems
to make power with less boost, which
is / has less tensile load to the engine.

A/F and Timing and Vanos plays a important roll which I believe the
Cobb does, and the JB4 relies on the factory MAP.
I myself is on the fence on purchasing
a AP. The features of JB4 has a lot of features
That Cobb doesn't, but bottom line is what makes more
Power stage per stage?

Not really a fan excessive boost taper, I don't know if you can
Tweak the COBB or run an independent MBC like a
Hallman Pro RX to hold boost like 13 or 15 psi until redline.

I have asked BMS question and Terry replies very
quickly. I just feel like running both.
but the MAP 5 is kinda weird. Boost fluctuates
and not consistent.
