I've pretty much got my truck tuned the way I want it but when it comes to nailing it rolling the only way it will kick down to first gear is under 20mph. Anyone know how to adjust the downshift mp? Its a 2010 silverado 6.2l 6 speed

Im thinking its about 42 43 mph. Does that affect the WOT downshift? If so how can I correct it? Id like it to hit 1st at least between 25 and 30 mph

sorry, thats not something easily adjustable in the parameters, might be a good idea to look into a custom tcm tune.
Thanks
