The best way to tune is either just use the canned tunes from the programer or take it to a dyno and actualy do a real tune based dyno results.

should I finish building her then take her to a dyno?

so in order to feel the HPs from that throttle body I need a tune?

You need a bigger engine to feel the benefits. 7hp is small enough to be considered a variance in the dyno itself. The stock throttle body flows enough air for a stock engine. The only reason everyone talks about increased throttle response is because the bigger throttle body allows more air in at less throttle angle. But at WOT there is no difference. If the stock engine only needs 700cfm and the stock throttle body flows 750cfm, then it's not a restriction. You can put a throttle body capable of flowing 1000cfm on there. The engine will still only need and use 700cfm.

The best tune is the one you do yourself. No tuner will spend the time and care as much about your car as you do. Plus if you have the software you can make adjustments as needed. You won't have to pay a tuner each time. Get everything worked out then figure out the tune.
