Best ECU tunes and Flash devices

I am finally getting around to adding a little spice to my SVT. So far the list of upgrades will be a K&N Typhoon, (Short) Screamin' Demon coils, and a throttle body, ( not sure what size is best ). I am looking to flash tune the car to work with all of the changes. Any advice and contact info for tunes and flash devices is appreciated. Also your personal experience with the tuners is a plus.

Thanks
