shift points... kinda...

i got a new tranny from darrin (thanks again) and i know that if you don't have a tune, they shift sooner. mine doesn't shift too soon, so i'm not that worried about it, but when it shifts into second, it seems to drop way too far. i, of course, want it to shift at the end of the power band and start again at the bottom of the power band. but as it is, it drops completely out (down to about 2.5-3 K) and takes to long to get up to third. what's the best way to get it to shift down to 3.5 - 4 K? a tune, gears, better intake, exhaust, just more hp? i really want to feel it snap my neck back into 2nd.

Well the gear ratios of the trans aren't going to change. If you shift out of first at a higher rpm, you will be at a higher speed and therefore it will be at a higher rpm in the next gear. A looser converter will also help because it when you are flooring it the converter is unlocked and if the stall speed is 3K rpms, then the engine will rev up to 3K when you shift into second even though the gear ratio would have it about 2.5 because the converter will allow that extra slip to get you into your powerband quicker. So from the sounds of it, you want a higher stall converter to get you up into your powerband quicker and a tune to let it shift at a higher rpm so that you don't drop down as low when it shifts.
