What Shift Points settings for Hypertech Programer?

Can anyone tell me from experience; what to reprogram my shift points with a Hypertech Power Programmer, on my Sierra. It has a 4.8 liter engine, Flex-a-Lite Fan, throttle body spacer, throttle body bye pass, K&N air filter, Flowmaster; sitting on 20 x 8.5 rims with 275/45 R 20 tires. I know someone out there has the same set up. Please share with me.
