What kind of hp and tq #'s can you expect to gain with a diablo or sct handloader?

Ellik

you mean with a canned tune, or using them in conjunction with a dyno for a real tune?

Not sure what you mean by canned? Just wondering how much more power can I get out of the motor.

usually those tuners come pre-loaded with a generic tune for your mods. You will pick up a little bit with that, but they are VERY conservative. Maybe 10rwhp. who knows.... To get the best out of the tuners, you need to find someone with a dyno who knows what they are doing to tune your car. They will monitor air/fuel, timing, etc. and get you right where you need to be. Again though, the more mods you have done the more you will benefit from a tune.
