How exactly do you hack the MAS?

People don't hack the 2G MAS very often. They can handle 3000hz and 450whp stock. You have to start hacking the 1G MAS pretty early on if you want to continue to use it and make any power. It likes to start overrunning when you get close to 2000hz. On a 1G MAS, the first steps are to remove the lower honeycomb and back out the calibration screw. If that isn't enough then you can start removing some of the lower half of the MAS with a dremel. People often at that point also solder a resistor or potientiometer into the intake air temp sensor line to fool the ECU into thinking it's colder outside and adding more fuel to compensate for the added airflow that it won't be reporting to the ECU. You don't want to hack the MAS more than you currently need because you can run into timing/knock problems and it gets hard to tune the more it is hacked. You also never want to remove the main honeycomb, without the main honeycomb it won't meter the air worth a crap.
