Before I pull the trigger on this, I would like to know if fuel is controlled/flow is increased by the unit istelf, or what exactly happens. How is this compared to the JB4? I have seen your comments that it's a similar board to the racechip, but the tuning is different and optimized for USDM vehicles. One thing I've noticed and whats kept me away from the JB4 is detonation on 91 octane with their maps offered with the device. Is this optomized for 91 octane? Is it reccomended to have plugs with a smaller gap due to the increased boost levels? What protections does this offer besides the factory knock sensor/timing changes? I currently have a 2022 G70 2.0t I am using as a test mule for modifications and writing a comprehensive guide to modifying the G70. I'd love to purchase this product if I feel it offers significant gains over stock and is 91 octane safe.
