That was me...I liked it and whoah what a difference, but honestly unless I had an AWD truck like my old Sierra Denali, you needed to be at the drag strip to really need/want those shifts. The truck would constantly blow out the tires at every intersection and the shifts would slam you b/c the engine torque management was basically gone. I kept the 93 tune installed, but went back to stock shifts and it's been mint.
Maybe I should have Mike set me up with something inbetween on the shifts.
Also FWIW, when I go to my place in Northern NH they only have 91 so I am blending, and have yet to hear or feel an issue.

I do have to say I have seen Jeff replying on this thread left and right, but when I DID have questions and tried to call that was not smooth, so I went to email and some times I had to RESEND the email before I got an answer from Mike and the way the answer was constructed was not so much disrespectful, but it certainly came across as condescending and just not friendly...like he was NOT glad to reply/help. I understand busy, and I understand guys that LIVE and BREATHE this stuff might thing one of MY questions is stupid or beneath them, but without us...they are not in business.
