Then you need to edit Game Data.
And there are several ways to increase BHP.
1. Swap engine from another car.
2. Increase the BHP value of some part example turbo but this affects badly on the RPM Range.
3. Use multiplier, this is the best way.
All this can be done by using Brute Force Save Data and HxD Editor.
Few other thing you can do by editing your save.
1. Edit money/Rank.
2. Edit you DLC:s so you can install them again(endless DLC paints).
3. Reset cars back to 0/0/0 cars.
4. Paint stock rims on few cars. Only few working cars unfortunately

5. Permanent borrow glitch without going into patch 1.05.
6. And much more.
