So taking a lot of JB's out of N54's these days & flash tuning. Customers are doing their own independent dyno's and coming to flash & going back to their local dyno's to verify they gained power.
This particular customer has JB4 & this is his gain over stock at KAR:
So JB4 gained him around 45 wheel kw & around 95NM.
He had some issues with the JB, got it resolved & added our custom 76mm downpipes. Still with JB & octane + downpipes he made:
263.5kw & 517NM on the wheels. Today we loaded our map on this car & this is what it made vs what it made last time on this same dyno with JB:
But to be fair we need to compare to the last dyno a ALB. So:
With JB: 263.5kw, 517NM
With Xcede: 296kw & 655NM
Both times with octane.
Here is the stock map Vbox:
13.3 @ 169.
Here is the JB4 Vbox:
Here is the Xcede map Vbox:
All Vbox's done with the same fuel in the tank and all with 2.1 60ft's.
