I changed gears from 373 to 410 and my shift points have changed. i won't to get it back to where it should be what can i do? Any idea's

i dont know what the vehicle is but i did the same thing with my 96 silverado then i just installed a superchip which will allow you to change your gear size, shift point, and if you have a 97 or newer it allows you to change you line pressure in your transmission plus its a nice performance add on as well...just ask all the fords down the road.
