We're excited to announce the availability of our own flashing software named "Belle" for most 1996-2013 GM vehicles.

If you have access to a laptop running Windows, you can now purchase a custom calibration for your vehicle, choose the "load-it-yourself" option (if available) and you will be sent a cable along with our software and instructions for obtaining and uploading your custom calibration.

As part of this announcement, we would also like to offer a $50.00 rebate valid through 12/24/2012. You will receive a $50.00 refund on your payment if you choose the "load-it-yourself" option and e-mail us a picture of your car and comments about your experience.

After significant research and development, we have finally dyno-tuned our 2005 Cadillac STS (LH2) and we would like to share our results as well as announce the availability of engine and transmission tuning for 2004-2006 Cadillac STS (2005+), SRX, and XLR cars.

Video of one of the runs:

The car gained 17 RWHP and 16 RWTQ at the peak of the horsepower curve and significant gains throughout the entire RPM range. Dyno graph available here

While we had the car on the dyno, we have also done a top speed test, the graph of which is available here. Governed by the rev limiter only, this 3.23 gear equipped vehicle reached 165 MPH.
