Messing with the shift pressure is a good way to mess up your trans. I just spent $400 repairing the 4L60E in my Blazer because of a programmer.

If I were you, I would just adjust the engine settings and leave the trans alone.

if more power is what you want then sell the superchip and get a custom tune from someone like nelson or blackbear performance. it will be like night and day. you can adjust your points and pressure just remember that you have the 4l60 trans, its not very strong when you go beating the crap out of it.

good luck

While I only have a predator, I have to say the best thing it did for me (after adjusting my axle ratio PCM data) was to lower my hot idle by @100RPMs.(a nice gas savings, not to mention a great early warning if my tune-up is headed south)

BTW,feedback seems conclusive, if you really want to go this route, Nelson Tunes or Black Bear is the way to go, hands down.
