You can increase power through ECU tuning in a variety of ways. Most manufacturers leave some room in their tune. It could be due to not wanting to interfere with the mechanical limitations of the engine or it could be to meet emissions requirements. ECU tuning modifies the fuel and spark maps of the engine.



Like downpipes, upgrading the exhaust will eliminate the restrictive factory cats. Backpressure will be reduced and the result is more power. At idle, sound coming from the exhaust is subtle and slightly louder than stock which then transforms into a deep, distinct sound at open throttle.



By upgrading your downpipes, you are eliminating the restrictive catalytic converters of the factory downpipes and back pressure is reduced significantly. This results in faster spool, an increase in power and more aggressive sound from the exhaust.

Upgrade your factory intake with a performance intake kit featuring higher quality filters. This will increase flow in the mid to upper RPM range and introduce a more aggressive sound from the engine. Your vehicle can gain up to 20whp just by replacing the factory intake system.



Upgrading your vehicle’s entire suspension system is not necessary. However, there are some parts that may need to be replaced in order to get better handling and driving out of your vehicle. Some of the most common suspension parts are springs, shocks, struts, shock absorbers, and suspension support. Many car enthusiasts will upgrade with aftermarket or import parts in order to enhance the performance of their vehicle.



Your vehicle’s braking system was designed for normal, everyday driving at the stock performance of your engine. This means if you increase the engine’s power, you need to upgrade stopping power to accommodate. The hotter your brakes get, the less power they have to stop, and they could develop brake fade.


These are just a few of the Porsche tuning and Porsche upgrade items to get you started. There are lots of different Porsche upgrades and Porsche modifications we can do for your car.
