While performance chips can increase an engine's power in certain conditions, drivers should not expect drastic changes. Some chips override manufacturer settings designed to increase the life and efficiency of a car's engine, resulting in higher maintenance costs and poor drivability.Know More
A performance chip upgrade is one of the least time-consuming car upgrades available. These chips are designed to tweak the default settings of a car's engine control unit, or ECU, resulting in more power, better fuel economy or a smoother ride.
While chips from reputable companies do work as advertised, performance improvements are limited by the engine's components. In some cases, the increase in top end power comes at the cost of power in normal driving conditions. Furthermore, the increase in power puts more stress on these components, leading to faster wear and tear. Finally, some chips disable emissions systems to achieve power gains, which may be illegal.Learn more in Car Parts & Maintenance
Putting mothballs in the gas tank does not improve a car's performance. That was not always the case, though. Gasoline used to have such a low octane rating that adding napthalene, which was the active ingredient in old mothballs, did in fact increase the octane rating.Full Answer >
A loose alternator belt will affect the alternator's performance and will lead to automotive electrical failures, such as dead or weak batteries, dimmed headlights and engine stalling. Common signs of loose alternator belts include a loud squealing sound, improper voltage and flickering gauge lights, according to Pep Boys.Full Answer >
A true dual-exhaust system helps to improve the performance of a V-6 or V-8 engine by splitting the exhaust from the two banks of cylinders. However, it is less effective on smaller vehicles that use an inline four-cylinder engine. The system reduces the pressure to expel the exhaust fumes, allowing the engine to send more energy to the transmission.Full Answer >
A bad mass air flow sensor in a vehicle makes starting difficult and affects the performance of the engine because he engine-control unit uses data from the MAF sensor to balance the fuel ratio the injectors deliver to the engine. A bad sensor returns a significantly different temperature than that of the engine coolant when read using a scan tool set to temperature.Full Answer >
