'VERY' common questions regarding to tuning the GP?. Including all engines?.
1.9 Mjet:-
Remaps - The ECU can be remapped which changes the engines 'fuel' & 'boost' mapping which increases power by around 40Bhp and increases torque dramatically. This will also lead to increased economy when driven 'normally'. The warranty will NOT be void UNLESS there is an issue that causes them to throughly 'examine' your ECU and they realise the remap is there (Very Unlikely).
Most common companies that do remapping are:-
GSR / Red-Dot - http://www.gsr-uk.co.uk/ They get nothing but good feedback from everyone who gets their car tuned. They also do rolling road runs before and after to proove their remap's with hard results.
Angel Tuning - http://www.angeltuning.co.uk/ People seem to get mixed results with angel tuning. The only benfit is that they come to you. You do not however get rolling road runs before and after remap. There has also been a couple of reports of various componants breaking shortly after remap.
Celtic Tuning - http://www.celtictuning.co.uk/ Don't know much about these guides but haven't heard anything bad either... Maybe someone has some reports to add?
Induction Kits - This involves replacing the standard Fiat OEM airbox and intake system with an aftermarket solution. These are not to be confused with the replacement filament filters you can buy (which don't really do anything). These kits remove the restriction on the air intake which allows a little more power to be produced, For best results get it install same time as remap. On diesel's they also help reduce the amount of black smoke produced under open throttle.
Only company the does a aftermarket kit (as far as Im aware) are GSR:-

Suspension Kits - This involves replacing the suspension coils / springs with a set that are usually shorter and stiffer ones. This lowers the centre of gravity and increases stiffness, this as a result improves the cornering abilities. If your lowering more than 35mm several people recommend aftermarket shocks too as the OEM ones will wear out faster. There is also the option of a full 'CoilOver' kit, This allows you to fully configure your suspension setup including ride height, camber, toe-in etc. Places to buy:-

.
Brake Upgrades - This normaly involes replacing Brake Disks and or Brake pads for upgraded ones. The disks are normally grooved and or drilled which allows for better bite and reduced brake fade and pad glazing. The pads are normally made of a better matterial that withstands heat better which also reduces brake fade. This can be bought from:-

1.2, 1.4 8v & 16v:-
All of the above applies to cars with these engines except you can go further and get the following done also:-
Reprofiled Cams - This changes the angle of the cam lobes and opens the valves further allowing gases to flow more freely.
Only company I know that does these on the Grande is GSR - http://gsr-uk.co.uk
Cylinder Head work - This involves the cylinder head getting ported, gas flowed, pressure tested and skimmed. You can also go further and get multi valve angle cut also. All this aids efficency within the cylinder head and allows more power. Also the only company I know that does this on Fiats is GSR - http://gsr-uk.co.uk/engineering/pages/productsbycar/fiat/fiat_pun_engine.htm
Aftermarket Exhausts - This involves replacing the standard OEM exhaust with one that has different flow characteristics and allows for more power be removing restrictions. It is recommended you do not De-Cat your car unless its a Turbo as this drops back pressure too much and causes some negative effects such as bad emissions and loss of bottom end torque. You can however replace the standard Cat with a aftermarket 'Sports' Cat.
The best for Fiat seems to be supersprint and they can supply a whole system which can be bought here:- http://www.motorsportworld.co.uk
