fuel pump and throttle body

[nextime]

do you know anything about a paxton MISTER gtsr515 on a stock engine? first it comes with a vaccum regulator that controls fuel flow in boost, second it only can be fed nothing less than 91 octaine or it will go boom, third the paxton i got is designed to run on a 100% stock system WITH NO UPGRADES. fourth i have 68,000 hard supercharged miles with no problems no holes in pistons. i am not running 10 or more pounds of boost to even worry about a blown engine and i think the enginer's at paxton know what they are doing when they said i dont need any upgrades. all i was asking will a 155lph run corectly without changing my stock that is doing a wonderful job regulator and what throttle body to get i wasnt asking for anything else and still nobody has answerd my questions except for my throttle body so thank you MUSTANG17 for the throttle body answers and also thanks PKRWUD for the insight on the new pump needing a FPR to run smooth.
