Default 475RWHP....help me break 500!

Just got my car tuned this weekend and she put down 475/475. I'm looking for some fairly inexpensive mods/tweaks to break into the 500's. Any suggestions would be great!!

Quick Rundown of the mods,

LS3 Intake
92mm TB
235/242 .635/.615 112 LSA
Pacesetter 1 3/4" Headers, 3" ORY (catless) flowmaster muffler
PRC Ported/Polished LS3 heads

Spray it, assuming your compression ratio is favorable. That or an E85 conversion or race gas tune.

1 7/8 headers and a true dual setup would help your power some.

Id go with the headers and true dual setup as well, might be able to get you to 500. Not sure what all you got on it but may a UD pulley, FTP lid, or a fast intake. Depends on how much you want to spend!

Cut that blowmaster off. I bet it'd help more than you think at that power level.

And dyno in better air if possible.

bigger cam and bigger headers will help a lot. headers for sure.
my 402 picked up 10/15 just switching from 1 3/4 P/S to 1 7/8 Kooks and getting the tune tweaked a bit.

UD Pulley, get rid of slowmaster, headers. Not sure if you have a lid and just didn't mention it but that would be good too. That should get you there. Or you could just go with spray.

If it's the Pacesetter ORY and the typical Flowmaster, a better Ypipe and bullet muffler, or an xpipe and some duals will more than likely get you there alone (of course with some tune tweaks for it)
