Where to Start on an LB7?

[LBZoom]

Hey guys,
I've got an LBZ that I've been tuning and it's going rather well...a buddy of mine wants his LB7 tuned and the tables seem a lot different so I was hoping someone could tell me where to start adjusting? I'm looking for a good 50-70 horse gain for towing, but would like a have 100 horses added when at full throttle. My LBZ lets you type a torque value in based on throttle position and it will deliver the required amount of fuel without much adjustment to a certain point, 812 lb ft of torque is max before you have to adjust fueling....the LB7 of course doesn't have a table like this...so like I said where do I start making the power at? The injectors seem to be okay, my buddy said the original owner had them replaced under warranty... Perhaps someone could send me a tune similar to what I'm looking for? Thanks guys!
