NOTE: If you are also getting a Mail-Order Tune, you do not need to purchase the VATS/Passlock delete separately. It is included in the Mail-Order service, just be sure to request the option when filling out the Custom Tuning order sheet.
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 before sending in your ECM as there may be additional charges. We do not have support for 1994-1997 LT1, 1995-1999 Vortecs, or any Ecotecs.
