If you would like to remove the often-failing Passlock/VATS system from your ECM, please use this listing. Send in your ECM and we will disable it permanently. Turnaround time is usually same or next day. We support almost every LSx, 4.2L GMT 360, 2.8L, 2.9L, 3.5L, 3.7L GMT 355, Alloytec V6’s from 1998-2004, etc. If you are not sure if we support your vehicle, please ask first. S10 and full size 4.3 please use this listing – link. NOTE: In a few odd operating systems, the security light will continue to illuminate even though the system is deleted. This is a rare occurrence. If this is the case (after being flashed by us) you may need to remove the bulb from the dash to keep from illuminating. The vehicle will still start as normal. If we offer mail order tuning for your vehicle, we can delete Passlock/VATS. If you do not see your application listed in our tuning system, please call or send a message before sending in your ECM as there may be additional charges.
