I3 Diablo tune

[Bamatechjon]

I have a 2004 z71 5.3 4x4 3.73 gears front and rear , If I install the diablo tune , change speed limit to 130 and upshift vs tp
to 3 percent 1to2, 4 percent 2to3 , 6 percent 3to4 I noticed that when slowing down turning usually 15 to 20 mph the truck has no get up and go it sounds as if its bogging if I hammer down then it will shift to 1st and haul butt , other wise it takes for ever to gain speed any Idea if its my settings , I do not notice this with stock tune .

that upshift vs tp param has a strong effect on hos the trans behaves at part throttle, id try undoing those changes....
