I have a 2000 Tahoe LT 5.3 4wd.Now I have a Superchips 87 octane program in it and i would like to know if adjusting the shift pressures etc. would help up and down shifts,as one member mentioned that quicker down shifts would be much better.Any help and explanations would be great and the trans has been updated and rebuilt.

does it have the ability to firm up shift points? If so, then yes, to a point.
