Keep the W213 E63 vs. F90 M5 videos coming! This matchup is a short but interesting highway pull as the W213 E63 AMG S has an M177 ECU flash tune from DME Tuning. The car also has downpipes which we assume are catless.

The F90 M5 is running a BMS (Burger Tuning) JB4 box set to Map 2. This is roughly 23 psi and it also has downpipes plus an intake.The E63 S edges the M5 but it would be interesting to see a rematch with the F90 M5 sporting a BCM (boost control module).

This is but the first of many such battles.
