Registration was the hardest step up the power upgrade process.Updating the Cortex 2950 via internet was simple.The programming process was just as simple. Great product that lived up to its promise of added power and increased performance. Joe

Good stuff. Installed easy, very noticable power increase, lots of extra data logging features etc. Hopefully the 93 octane tune will be here soon, but a definite good power adder. Buy it and forget about he Stage kit Chevy will never release and if they do...it'll be overpriced compared to this.
