Modifications
For each truck and engine you can add and make adjust who you want it. The moat common thing people do to there trucks is add a turbo. What the turbo does is add more HP. It does this by letting air in the middle and the more it spins the more boost you make and the more HP and torque your tuck has .he other most popular thing people do is add nitrous to there truck. What nitrous does is add also Hp and torque but this only added it for a few seconds. Also this does not last for long because the bottle of nitrous only has 10lbs but there are bigger but more expensive. I would recommend to buy a turbo more than a nitrous bottle but both of them combined is also good. If you want a turbo you can have one really big one or multiple small ones.
