BA XR6T / F6 STAGE 1 – 270RWKW

​Our stage 1 package touches on the few things that we believe could have been addressed better from factory, obviously they weren’t due to budget constraints or similar. But firstly we fit our PR Spec 800hp rated intercooler kit and Under Battery Intake. These together address the heat soak issues that are evident in stock form, our kit makes the cars performance repeatable and consistent, we also upgrade the fuel system to include flow matched 1000cc injectors and a high flow in-tank fuel pump module, this ensures that we supply enough fuel to the engine when raising the boost levels.
