why are the numbers so different if they are so similar?

The 5530 is considered their aftermarket upgrade, while the other is in their hp series..
ask pte i cant understand it either.
i needa drive my car, i cant even remember when i hit full spool at, maybe 4300 rpms sound right with oem cr?
My 5530 has a billet wheel and I'm running 9.5:1 comp. idk ic that makes a big difference.
Yea I mean I'm running als billet upgrade 3071.. the drop in cr helps a lot with spool, ill prolly take a ride tonight....I'm guessing a jump in charge pipe from my 2in will do the trick.
X2, but man does it suck to have a downed car. Going to miss another weekend of racing because Comp Turbo can't get their shit straight.
