Example Power Output (B58 G2)

These are some example power ranges we have seen on a number of vehicles. Power numbers are estimates and a wide range of variables can alter the acutal output. All dynos read differently and fuel quality / climate can alter output. Power is not gauranteed. Chart is only for an estimate of power gains.

  • *Power depends on finely balanced ethanol content, peaking at 25-35% and quickly falling off due to fuel pressure

  • **Heavily depends on tune aggresion, desired power, transmisison, and optional port injection fuel pump upgrade

  • *** Tunes with + option would assume port injection installed. Tunes with auxiliary fuel pump or methanol can run E85. This requires a consult for goals

  • **** Power output is an estimation based of many dynos we have seen. Power is not gaurantee'd. Many variables can alter the reading and all dynos read differently.
