Upgrading from an evo "7.3"

[PowaStroka]

OK so I have a few more questions before I order.

1. On stage 3 of the evo, I like the low end and mid range, but the truck is really flat at full throttle, with high egt's and alot of black smoke. What gryphon tune is closest to this tune?

2. On stage 2 the truck looses a low end and gets a little worse fuel mileage, but feels much better at WOT. "not really a question I know"

3. I rarely use stage 1 if ever because I don't tow anything that would make me take it out of stage 2/3

4. In the winter the truck does do some moderate plowing. And this summer I would like to take it to the dragway without killing the EGT's

I guess the question at hand would be what would be the 3 best tunes for me?

Mods are as follows:

6637 air filter
4" turbo back
Edge 15001

Thanks in advance!
