Wow, your car pulled ~ 1 G in initial acceleration, impressive.
Shaved .2 sec on 1/4 mile and picked up 2 mph of the C&D results. C&D Probably ran this test on cooler less humid day (December in CA). On a cooler day you'll put down even better figures.
Wonder what the intake temps are...
[Tires screeched slightly.].
Sounds perfect, as with most mid-rear engine cars, massive about of traction under launch conditions.
Brooks with Drag times and C&D recorded 3.4 s to 60 (stock). Brooks mentioned a 3.3s. Clearly your putting down better numbers with your mod.
Probably need...
Doing some research on the latest AMG M139 engine. Looks like the M139 can operate at higher boost. Assuming proper cooling. Latest version operates at 40 psi. Emira version is already at 9 to 1 CR. Factory power output is rated at 469 HP, this engine might also have a very larger...
Very true, last time I increased boost significantly on one of my cars; I had to up the intercooler (4 times larger, with a larger intake air duct). Yes, people should be careful.
I do wonder - with the piggyback essentially overriding the boost value (both cars) sent back to the ecu. Will...

[That's strange, we hit 2.5 bar on another piggyback.]
This is what I was expecting 2.5psi is about 36 psi, you must be pushing 500hp at the wheels.
Do you have a draggy ? with 500HP I bet your able to dip into the 2s for 0-60 subtracting roll-out on a nice day.
Which piggy -back...
High level your system is raising boost levels about 4 psi off stock config. thanks
Interesting that Mercedes indicates the M139 turbo produces
[Peak boost is just under 30.5 psi for the S engine trim and just over 27.5 for the base engine.]
Of coarse no gauges on the cars to confirm.
Exactly, someone should pull back the loom take a picture of the wire colors and find a good place in the harness to splice in -
Better yet the JB4 guys should weigh in on the best place to splice in - maybe even provide water proof splice connectors in the kit or OEM plug adapters with quick...
With this connector being so difficult to access, maybe follow the wires to more accessible location and splice with some water resistant quick connectors.
[it from swiveling forward like in BMS instructions.]
Well that's unfortunate. Earlier in this thread a clever member documented using some custom tools to pull out. Might want to try his approach.
[dynoed stone stock on a hub dyno, and it showed 369.6 hp to the rear wheels.]
Eagle7 did you add the JB4 module to your car? If so are you planning to re-dyno, would be nice to see an independent comparison.
