'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.

This thing is fantastic. It saved me thousands, because I was ready to trade my Tahoe in it was so frustrating to drive. This thing completely changed the vehicle and now I love it. Feels like it's 1000 lbs lighter. Great throttle response, a lot of power if you need it, and better manners on the highway. I chose Performance program. Gas mileage unchanged overall, but more & predictable power. Heck of a deal. Puts a smile on my face when I drive now.

This is my 3rd Hypertech purchase and the most significant need to fix a factory dog. The difference in performance of my Tahoe, before and after is incredible. The installation woke up the engine and gave me a fun vehicle to drive.
