When tuning the Turbo Porsche vehicles such as the 996 and 997, there is a limit of what boost you can run on the stock engine.  Boost pressure is definitely what can turbo the power up, but if you are using pump gas, detonation can occur.  When asked if you need to retune the car if running a water/meth injection kit, the answer is no.  Since Softronic tunes off the factory knock and oxygen sensors, they are controlling timing and at any sight of detonation, timing is pulled back.  Water/Meth injection is simply a replacement for running race gas.  It allows you to run higher boost pressures on pump fuel without detonating.  Another good feature of water/meth kits is for those users running 91 octane, you can get the more aggressive 93 octane map which has more timing to give you more power.  If you decide to run one of these kits, make sure it has a good fail safe system and do not use chemicals that can be corrosive to injectors and engine internal parts.

The factory intake has a waffle looking screen that goes betwen the MAF and the intake box filter.  This keeps the airflow that goes past the MAF laminar or “straight”.   Turbulence can cause that very sensitive MAF sensor to fail.  Another cause of the MAF failure is over oiling your aftermarket filter or touching the sensor and getting “dirt” on it.  Make sure to only handle the sensor by the top plug and never grab the sensor part.

The 996TT MAF controls many applications in the car, when tuned properly, these can handle up to 800 horsepower at the crank.  Remember to always run a diagnostic check on your car to see what codes may come up.
