Tuned PCM for 2004-2005 Northstar V8- Bonneville, Seville, Deville, DTS

Replacement PCM for 2004-2005 Cadillac Northstar V8.

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. Speed limiter is removed and rev limiter raised. Performance enhanced, approx. 30 HP over stock.

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.

Installation is easy. Relearn procedures required: 1. Key Security Code Learn. 2. Crankshaft Position Relearn. Need dealer level tools such as Tech2 or Mongoose cable for this. If you send your PCM in for the tuning, no relearn is required. Key learn on US domestic market vehicles can be done in 30 minutes in your driveway. Canadian or international vehicles will need dealer level tools for this.

This PCM will fit the following vehicles:

2004-2005 Pontiac Bonneville GXP
2004 Cadillac Seville SLS / STS
2004-2005 Cadillac Deville, DHS, DTS

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