General B58 performance tune

[agcheck]

There is a Burger JB4 available for Grenadier. This will be the most aggressive tuner available, most likely.

Not looking at a piggy back....flash tune.

Bringing this back up since a couple of companies were successful flashing the ECU after unlock. Dealer in Germany and Gren X in Australia offering Diesel tunes, Buzz Overland apparently did a B58 to 460HP.
Is anyone in the US working on this?

The Buzz overlanding seem promising. The original way to do it was to send ECU out for unlock and have a company bench tune. Meaning you could not tune via OBII, so I'd be curious if Buzz's tune is this method or not?
