PCM tuning a 2007 GT?

First post after my introduction earlier today.

I´ve bought my 2007 GT a couple of weeks ago and I really enjoy the car.
Started thinking about tuning the car as we here in Sweden have 95 octane as regular gas and the choice of using 98 octane.
The car is all stock, nothing done to it at all and it has a mileage of apr. 50000 miles.

I think it will be hard to get a custom tune here in Sweden so I would like to hear what you here at the board would recommend?
What and where to buy or what I can do myself?

You would need a pcm out of an 05 to tune your car. Your gas gauge will read backwards after you swap the pcms. Hptuners is what I would recommend if you want to tune your self.
 
Your gages wont read backwards, i recently did at PCM from a 2005 Grand Prix GT to a 2006 Grand Prix GT and all my gauges were like they were before.
 
I can confirm that on the 2007 Grand Prix, using a 2005 VCM the gas gauge does in fact read backwards.

Have you driven the car for awhile after tuning it? The gauge looked fine for me until I drove the car and used up some fuel.
