Superchips Cortex Programmer Reviews


'03 Z71 Tahoe, 5.3L V8

Reviewed By Thomas P (Shreveport, LA) Reviewed for a 2003 Chevy Tahoe —9/8/2011 1:46 PM

Just crossed 150k miles on my Black Mamba. She felt so dang tired compared to how peppy and zippy she was brand new, so I started looking for ways to improve my performance. Wasn't looking for a race car (it's a Tahoe, for pete's sake), but I wanted to be able to floor it across an intersection from a stop sign if I had to without feeling I might get hit by traffic. Superchips was able to help. I installed the Performance tuning (haven't tried the other tuning options yet) and now she's quicker off the line, has muuuuch better throttle response, shifts much harder (sometimes I even wonder if she shifts too hard and I'm hurting the transmission maybe), and I can definitely tell there's much more power throughout the entire range of RPMs. It's especially noticeable at slower speeds (at 20-50 mph increased power is certainly noticeable when I give it some gas). Installation was a snap, followed the instructions and it took a total of about 10 minutes. When it initially started installing, my warning lights all went nuts and scared me a bit, but it all returned to normal after installation was complete. All-in-all, I recommend this product for anyone looking for a bit more excitement and functionality. Next I'm going for the K&N performance intake.

I am delighted with my latest Superchips Flashpaq Tuner, this is my 3rd flashpaq tuner from Auto anything. If you have ever hesitated to purchase one of these tuners for fear of the installation process, hesitate NO longer, if i can do it ANYONE can. I have nothing but good things to say about Superchips and AutoAnything, I have and will continue to highly recommend both of these quality companies!
