Car looks nice mate

You've got the GRS so charge temps won't be a prob.

I would say Chipping the ECU would be the next step so you can run the car with more boost I beleive without the chip you can only run the car at 10psi (could be worth changing the actuator to a -31 while you are there if the one on there is old). With a chip you should be fine for about 15psi of boost. Ensure the car is set up by somebody that knows what they are doing and it should feel like a new car. If that isn't enough you can start looking at camshafts and cylinder head work.


On a quick note though it may be worth checking what you can do to the car legally as I know the French powers that be get quite upset if you start tweeking an engine to increase its power output.
