HPIII Specific Programming Setup for Silverado 6.0

[mayhem]

I am getting a hypertech programmer this weekend and need some insight on what setting to use for my 6.0L. I'll have a lift and bigger tires so am looking for the best performence gains using the 89 octane setting. Anyone out there who can tell me the best settings they have found would be much appreciated.

Don't expect much improvement on the 87 octane setting, but try it, then try the 93 setting and see if it's worth it to you. Set the shifts to firm, raise the shift's +2 for 1-2 and +3 for all the rest, raise the rpm limiter to 6000, raise the tire speed rating to whatever you feel comfortable with, and of course, plug your new tire size in.

So how did the HPP3 turn out? Any big improvement?
