are mail order tunes good enough to tune a monster head/cam swap(trex or something a lil smaller) or big stall....i know to get the BEST out of it id have to Dyno tune the car....but for the time being could a mail order tune make it a driveable car on the street(no stalling out at traffic lights)

Mail order tunes are only approximate, id do it right the first time. I just think you would be happier than if you did it twice to get it right. Some of them also lock your computer so no one else can tune it, ive heard. This would be not cool. For not much more money you can squeeze out every ounce of power for the money you spent.
