APR B9 2.9T upgrade (RS5)

[s4tokyo]

Same engine, so I'm jumping to conclusion that similar upgrade is theoretically possible on RS4.
Another point of reference v's ABT and other EU upgrade options : https://www.goapr.com/products/ecu_upgrade_29t_b9.html

I had a JFA tuning box that pushed out 520hp and 560ft2 torque so the APR tune not that much different.

On a 'first owner' car, I just don't have the gonads to go this far:) ...and being in Japan & reliant on overseas Partner(s) for this type activity doesn't instill me with confidence either I guess.
[APR require Customer to ship them ECU .... although I presume this is similar for others with similar 'SW only' upgrade].

An interesting upgrade comparison as to what is possible. I expect their (typical) Stage 2 upgrade, incl. hardware upgrades, will be quite impressive.
