What do you mean by "tune"?

As previously mentioned:

DiabloSport Predator Hand Held Tuner: http://www.runninwiththedevil.com/fordgas.htm
OR
SuperChips Hand Held Tuner: http://www.superchips.com/html/products/ford/cars.htm
OR
SCT Extreme Flash Tuner: http://www.superchipscustom.com/car_info.php

If you want to get the most out of your mods, you have to tune the car for them. Yes, you will see significant gains by just bolting all this stuff on and running it "as is". There is a lot more "Free" power awaiting you by simply tuning the car to better utilize the modifications made.

Which one of those tuners is best for a 01 cobra? I was leaning to the diablo sport predator since it would read out live numbers too me and is backlit etc.

Would it be worth my while? Stock now but exhaust, gears, and nitrous in the future.
 
I made 401+ today with just a K&N FIPK.. $169 and a MagnaFlow Catback $329 in 100 degree heat, no tune.

Thanks U.M. for the recommendations on the K&N and MagnaFlow
