6 or 8 psi?

[chatcher]

i am looking at superchargers and trying to make the right choice for my car and driving style its a primarily stock car headers h-pipe(no cats ) and flowmaster exhaust. i guess the biggest ? i have is. is 6psi enough keep in mind i have never dealt with a supercharger before but i would say i am a 7 or 8 on the 1-10 scale for mechanicly inclined i do plan on heads and intake-tb and all those type upgrades eventually but i would like a noticble hp increase now i also would like to retain the stock t-5 as well as the 8.8 or should i just buck spend the extra dough and go 8psi my fear there is drivablity and tuning issuses should i be afraid probably not im sure i can work through those probs but id rather be driving it than working on it so any input would be greatly app thanks
