Yep i install DEI- Since you do have the factory transmitters, it will work just fine. It gives you all the necessary stuff like shock sensor and siren, but the only draw back is that you will only be able to turn it on or off with the range of the factory transmitters. Usually they will go only 20 feet or so. Have it installed by a reputable shop if you are not familiar with the cars wiring and door lock wiring..As far as the turbo timer goes, i don't think you will be able to arm the alarm with the engine still running with the timer, so you would have to arm it after it turns off.
