Which Gear and Programmer do you recommend?

[Nop5.0]

I'm sure these topics have been addressed many times so, my apoligies for bringing them up again but.....I just want to be sure I'm doing the right things. I bought a new 06 GT 5 Speed a few months ago and would like to change the gear. (I plan on running 275/40 17 M/T Drag Radials) The car is basically only driven when the weather is nice (400 miles thus far) so I'm not real concerned about fuel mileage. Mainly, I'm looking for quicker ETs without totally sacrificing drivability so, I'm thinking 4:10s or even 4:30s.
Also, I'm torn between the DiabloSport and SCT tuner. Any preference or are they pretty much equal. Thanks very much for your help.
