Looking for an alternative for my AEB to flash on a spare 557P ECU to replace Giac PC16 ECU.
Can't get car to run decent. Just want to swap the ECU to rule out problems on that end.

I run the 310cc injectors that the PC16 calls for. Stock MAF. K04 turbo (high flow manifold, 3" DP, FMIC, cat back).
Have 3 bar and 4 bar OEM fuel pressure regulators.

Alternatively: stock tune for 557P (but then have to change injectors (not sure if I still have stock injectors around) and solder.
