| That's odd, I have one for my 06 LBZ and after the update last month it shifts very well in all three tuning configurations. I like it. I just wish I could build the trans and go bigger, but it is truly a very capable tuner IMHO. As well as with the new update you have the ability to calculate 0-60 times and up to 1/8th mile times also.
