Stage 2 on the Cheap?

[MY95]

At cruise, no difference.

At full throttle, worse for full torque. More power requires more fuel. Laws of physics.

Is it a lot worse or only a bit worse? Even at stage 1 you can sometimes see the fuel gauge go down slightly when nailing it for 5 seconds+

Im looking to go down the limited torque route, still gets you the bhp the full torque map does but just not the torque, although you save the money from the clutch and also the longeivity of the engine a bit more
