You most likely have a CF3 - it has an electronic throttlebody rather than a cable operated one so that tends to mute things a bit. A remap can help but what really strangles the mid and top end of your car is the lack of a decent exhaust manifold & front section. You have a 4 into 2 manifold which is far far shorter than optimum and then bolted to that you have two cats. You can remove all this and go back to the CF2 manifold (it's a good bit longer) and front section without cats (less restrictive), it's a fair bit of work but totally do-able, you will notice a nice improvement, and a remap will finish things off nicely.
However you should start with the basics first and ensure that the car is already running optimally. Correct spark plugs fitted & in good condition, air filter is not dirty, MAF and lambda sensor operating correctly, throttlebody flexi pipe is not split, exhaust is in good condition, engine is serviced, no errors are present in the ECU, tyres are pumped up, etc etc. slightly more difficult to check is to ensure the cams are timed correctly. You need cam locks to do this but it's worth checking your timing belt cover to see if it has little tippex marks on it - if it has it's likely had a cambelt change by a non-specialist without the correct tools and will not be set up quite right.
