Well I have had one for a long time. The tapshifter works great but for shifting while sled pulling it lags to much it is not a good option for that. I also have the torque converter unlock switch that has never worked properly from the start. As far as tech support my calls were never returned. Like I said I love the tapshifter but for pulling def. not. the manual way to shoot forth is the only reliable way to do it or tune it in in efi live.
The lag between shifts is the tuning based. The TapShifter issues the command same as if you were moving your selector from 2nd to 3rd.
As far as setting them up to better control the up-shift, you need to tune the TCM so that you exceed your shift parameters quickly, that way when you give the command to up-shift, its ready to go.
The latest TapShifter was completly re-vamped and is much faster as far as communication goes, and as mentioned is 100% plug and play. It shouldnt take a novice more than an hour to install.
For you specificlly, we've not always been the best on the phones, we typically spend most days covered up with calls. Right now is our "slow time" and would be a great time to open up those lines of communication to see if we can get your AlliLocker functioning properly. If you call and don't get anyone, shoot me an e-mail
