    Thats pretty low torque results for stage 1...always seen figures closer to 280 or 290fpt so definitely more to come once he mods the map to your car mods.

    Boost pressure wise on the stock turbo its about a match...turbo max's out close to the rods normal limit but all depends on the rest of the engine...ie mileage and history for good oil changes and considerate driving style.
