Before tuning the 'tamer, be sure your pedal stop adjustment allows clean hi-rpm shifts, also try to make sure there isn't any obvious chassis setup problems that will compromise your potential. Shock travel and suspension issues are pretty common.
With 4.30 gears and not knowing what clutch you have, I would start with the outer knob 2 turns from zero. From there make some short 1 second clutch dumps off the pedal stop from 4500 or so...
...If the tires spin, turn the inner dial counter-clockwise a couple turns.
...If the engine bogs, turn the inner dial clockwise a couple turns.
Repeat until you find the line between spinning/bogging, then back off the inner dial one turn from there in the counter-clockwise direction. Don't go crazy, no more than 3 consecutive 1sec dumps without giving the clutch some time to cool. On a nose heavy car, a little 150 or so rpm flare on launch will give the car a little time to transfer weight before the tires see the full hit of the clutch.
From there start making full hits while incrementally raising launch rpm. When you have raised launch as far as you are comfortable with and the engine still bogs more than you like, then you can start adjusting the outer knob 2 turns clockwise per hit until the bog goes away.
The above will help you get most of what's available from your current combo as it sits. If you make any adjustments that improve the chassis, those adjustments may in-turn allow you to get more aggressive with your 'tamer settings.
