Review on High-Performance Chip/Power Programmer for Cadillac DeVille & DTS 4.1L, 4.5L, 4.6L, and 4.9L - Enhance Fuel Efficiency, Save Gas & Boost MPG, Amplify Horsepower & Torque! by David Jennings
Agree on spares
I have two caddies both with these chips. The one I use for cruising has the best gas mileage. Caddy number 2 has more horsepower. So the statements they give you about gas mileage and horsepower are correct.
Pros
- Amazing
Cons
- Some errors
