The kit makes 460whp and 440wtq at 12psi but has to run 93.. I might experiment with 91 but imagine it will pull a lot of timing and run bad.. we'll see. Definitely want to start out running what it is tuned for.

Buy the torque app and OBD2 and see if there is detonation on 91 octane. Also run 10% ethanol as extra knock resistance. Or you can run water/methanol injection like I do, octane on demand.
Also, the V6 stock timing tables are for 91 octane, but will pull timing like crazy on 87 octane. The V6 is over 11:1 compression ratio, higher than the LS3. It can run on 87 due to the knock sensors and direct injection.
