I don't know if this is the place to ask questions but I have purchased a U7191 for my Trailblazer SS and there is no difference in power and I have a 1-2 flare shift any info would be good.

The U7191 does n ot communicate with the TCM in those vehicles, so shifting should not be affected.
Try removing the tune to see if it goes away.

Thanks

you sure you got the tune installed? you should definitely feel/notice a performance/power increase...

I have tried uninstalling it and the vehicle shifts fine i have tried to install it again and i have a 1-2 flare shift. You are saying that nothing changes the tcm but something is happening.
