Can a Dynotune control shifting, TC lockup/slipping, etc....

I recently installed a brand new Yank 3K stall, Z06 complete rear, and Z shocks. Since then I have had nothing but issues. I have addressed everything I can think of and my tuner who uses EFI Live has been great, but I think we are missing something. Before the changes car ran great not a single issue. Now I have a CE light that points to my front ABS sensors. I can continue to address those but now I get the infamous AC warming message. Hell the car is garaged in CA where it has been 85+ all week. I started the car this morning and the tranny was already at 97 degrees. After I hit about 30MPH I get the service ABS/TC/AH messages. I think this is either due to it not really seeing the 3.42 gears or the combo of that and my 19/20 wheels. It was fine before? Also I find that my car hunts for gears. I can drinve around 55-70 and if cruising it will jump from OD to D. With EFI Live we did find that under exceleration the TC performed exactly like we wanted and would lock and unlock, but at 70-80MPH it was around 75 (don't know what this number is) and the EFI licve support said it should be under 40???? Tranny is getting WAY to hot and everything from cooler to lines has been addressed. so with all this I am curious to know if a good Dynotune could possibly resolve all my issues. I have been hesitant simply because I have a great guy working with me and using EFI Live, but I am wondering if I grew out of this stage and need a Tuner with a Dyno to get it done?

either there's wiring problems, or program problems. I myself used a handheld device when I upgraded rear gear ratios. Pretty much... one button push and all got accomplished that needed be.

Is there a forum somewhere that has a section dedicated to your specific programmer ???

If you get a dyno tune, than be certain to reinstall your factory tune beforehand. Give the dyno operator a clean sheet to work from.
