Needing a custom Tuner, but have a few questions.

[cmmurray05]

I have an 04 F-150 5.4 and am needing a tuner with custom tunes for O2 and air/fuel issues. I would like to know which tuner would be the best for my set-up. I am leaning towards the Gryphon, but still unsure.

Upgrades:
Cold air intake
throttle body spacer
long tube headers (No Cats) x-pipe into dual Flowmaster super 44's

I also currently have a hypertech (Waste of money) tune installed on my computer and my tuner was stolen with my factory settings stored in it. Will this be an issue? Or can they be wiped out with install of new tuner?
