Apparently it's done through hex with the GT5.0 file from your save (perhaps it has to be decrypted first) . I am going to begin experimenting now. If anyone gets on to something please share! And I will share any progress I make as well.

I can change the values and make them reflect on the actual car, I just need to know what bytes I need to modify in order to increase/multiply the hp past the cars 100% limit, that's ALL I need to know.

Heres a post from him on gtplanet...
Hi All,

I've got some modified cars for you to try.
PSN: SchewterMcGavin

Cars are Shared Online
I made these cars a while ago using a Developers Console and some debugging tools.
Recently I've seen 3 different players with cars doing 700 mph.

There are alot of possibilities to what can be modified.
It is likely the Online Experience of GT5 could be damaged/ruined.

I'm hoping Polyphony will spot this & issue a patch to prevent modified cars joining any race of any type.

When such a patch happens, there is hope for a Garage Editor.
(Which people can use with patches deleted)

So, I'm not here to wreck Gran Turismo 5.
Actually, I'm trying to make it better, as right now it is possible you can be cheated without knowing.

Now i asked him earlier if it's possible to do with out a dev ps3 he answered yes. Now i also asked him if it's possible through hex editing he also said yes but it'd be harder then with the dev ps3... Skyline what values you change to reflect on the car?

Just seen this before&after edit....
Laughed :\

and i bet it didnt do nothin

Sounds like you are very close young padawan. If I told you, you would punch yourself in the face (serious)

^ PM so i know and work off that :p


u still gifting cars out to borrow?

No he aint but he might be uploading one of his saves so keep a look out

You could upload a picture that shows what values need to be change and we take care of the rest.

Yes, anything that would help.
