I could hook you up with a small Tweak like program for some very basic tweaks for X (Change cylinder amount/engine power/engine size) for the XRT and XFG/XRG (Engine power/Engine size)
I'm still working on a decent method of finding the values and such, so I don't have many at the moment. Its currently for test patch X3, so yeah let me know.
See ya!
the turbo has to be like a 5000000mm size 
do the creators have leway on this kind of thing, like let me have the full version of v for free, i have already paid for x so they have my money and wouldnt be losin anythin
