Already tried programmer on 2008 SS Impala, no problems, but it seems that on this vechicle it won't connect. this also happened on a 2004 Escalade...Any thoughts?

Anything aftermarket installed in the truck? i.e did not come from the factory?

make sure anything aftermarket is disconnected/pull the fuse for - anything like aftermarket stereo, subs, amps, nav, alarm, remote start, seat heaters, trailer brake/light setup, etc.. anything like that, their wiring harnesses need to be disconnected/pull the fuses for it before you try to tune anything...

also make sure everything is turned off inside the truck.. lights, radio, heat/fan/blower, do not operate power windows, put your parking brake on, etc...

I am totally honest when I say, this truck is 100% stock, no exhaust, no CAI, no stereo (other than factory) All the power is turned off in side. door closed. All is done with the exception of the parking brake...and nothing happens.

if the trinity talked to the 08 Impala SS, you need to go to options/change vehicle type and select the 04 Escalade or 03 Yukon to change the application from GM CAN to GM J1850, then it should work.

Thanks
