This is a very basic .xml file edit of the Lizard 2014 pickup by Realistic Farmers (original on official modhub).
This is what I did:
Increased the horsepower from 300hp to 400hp
Increased the maximum speed from 120km/h to 220km/h
Increased the maximum reverse speed from 45km/h to 100km/h
Decreased the price from $45,000 to $30,000
Decreased the price for changing the main colour from $1,000 to $5
Decreased the price for changing the rim colour from $100 to $2
Increased the truck’s fuel capacity from 120L to 200L
This does not include the fuel tank that comes from the mod off the offical modhub but should still be compatible.
I haven’t tested it yet, but it should work. Let me know if you want me to do this with another mod.
