GM 1994–1997 LT1 PCM VATS Delete

We offer a mail in service to delete the Vehicle Anti Theft System (VATS) in GM 1994–1997 LT1 PCM modules. VATS will prevent your car or truck from starting after a security-system failure or an engine swap. The vehicle will crank but never start if VATS is active. VATS is good for PCM replacement, and engine-swap use. This service changes VATS only, but tuning is available through the link below.

Need more than VATS removal? The $299 mail-order tune includes VATS removal and performance tuning. Great for engine swaps, gears and tires, cams, and any other bolt-on upgrades.

How mail-order service works

Purchase this service.
Complete the service request form using your order number.
Remove and securely package your PCM.
We STRONGLY recommend that you use the white 9″ x 3″ x 12″ pen+gear brand boxes available at Walmart. They are strong, made in USA, and cost about $1. Most GM ECM and PCM fit in these perfectly. Just add a bit of paper on the ends to prevent it from sliding in the box during transit.
