Bully Dog Triple Dog GT Tuner (49-State Legal) Reviews


My two cents

Reviewed By Braden W (BELLEVUE, NE) Reviewed for a 2003 Chevy Tahoe —6/5/2013 8:43 AM

Currently using the regular gas tune running 89 octane. Noticed more power than running stock with 89 octane. Moving acceleration increased quite a bit but I haven't noticed anything off the line but my truck was already peppy in 1st w/3.73 gears. Highway above 55mph i have noticed roughly 5mpg better mileage and city driving 45mph and under its about the same or worse mpg probably because its kicking in more fuel. Currently watching intake temp vs outside to see if a CAI is colder!

Superchips VIVID Performance Tuner Reviews


Niiiiiiiiiiice

Reviewed By KEITH H (PHILADELPHIA, PA) Reviewed for a 2003 Chevy Tahoe —6/10/2012 8:50 AM

This works great.Instant noticable difference.Love the flexibilty for vehicle configuration(CAI,Modded Tranny, Catback).LOVED raising the 100 M.P.H. speed limit governor. Shifts firmer. Much better throttle response. Only issue I had was a few connictivity issues to my phone (Motorola Atrix)but once I went on Superchips forum I found the solution. I'm glad I waited until Superchips released the LinQ and didn't order the entire Vivid Paq with the Archos that's great for people without Anroid devices.Good to see that a manufacturer thought about Android users before iPhone/iPad users.

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.
