copy of Performance Tuned PCM for 1996-1999 Northstar V8

Replacement PCM for 1996-1999 Cadillac Northstar V8. Select factory or performance tuning for up to 45 additional horsepower at the driven wheels! This was dyno tested on a 1997 Cadillac Deville VIN Y (base model). Torque also saw a 40 ft lb increase!

We start with the latest GM calibration for your car and then add our performance calibration. This modifies many parameters including ignition timing, fuel curves, shift speed.

One of the best parts of this tuning, your fuel economy will actually IMPROVE by about 4 miles per gallon highway (based on reports from our customers and our own tests as well). This is because while we tune for performance, that also increases the efficiency of the burn in the cylinders.

With this performance tuning, you can turn traction control off and still retain 1st gear. All 96-99 Cadillacs lose the use of 1st gear with the factory programming if you turn traction control off. Try it, you will see.

Installation is easy and no re-learn procedures are needed at all on the 1996-1999 cars.

This PCM will fit the following vehicles:

1996-1999 Cadillac Deville & Concours
1996-1999 Cadillac Seville SLS & STS
1996-1999 Cadillac Eldorado ESC & ETC
1996-1999 Oldsmobile Aurora

Installation instructions are in the box, and we have a youtube video on this also. Here is a link to the video:

For standalone/sandrail/hotrod options please contact us- we can remove VATS and set you up for running a Northstar outside of the factory vehicle.

We also sell stock replacement units for less money, that have stock/factory programming on them.
