sensitive alarm

i just put an sti type ra tranny in my wrx with a lightweight flywheel and 6 puck clutch, now when i lock the car when the turbo timer is running still, the rough idling from the flywheel sets of the alarm....is there any way to set the sentitivity of the alarm....

The problem is the vibration sensor on the alarm is getting triggered.
You may want to have the sensor checked to make sure it hasn't gone faulty, once that is confirmed, perhaps consider a senson which is less prone to setting off by cyclic vibration.
