I have a 2002 Z71 with 196356 miles. I have a Bullydog GT tuner which I just love. I have noticed an increased exhaust note when running in performance mode. I also notice that my truck feels firmer all around. The suspension feels tighter and the shifts are markedly firmer. I have so much more power off the line and at speed. The transmission shifts are firm and tight which I have heard is better for your transmission. My tranny is starting to go as I am having slipping between 45-55 MPH but only when trying to maintain that speed going uphill. I have been told to try Tow/Haul mode to alleviate this issue. I will be getting a rebuilt installed in February.
