Good Dyno Numbers??? How to pick up more HP?

So like the sig says i have a K&N CAI, Jet MAF, Diablo tuner, MBRP cat back exhaust, cat delete and pacesetter long tube headers (1 3/4). and im making 425whp and 450 ft/lbs tq. is that around average? I didnt have to drop a fortune on expensive brands, but if i had what kind of power would i have gained. I would like to make 500+ whp. What kind of mods would I need to get me there? Any suggestions?

What kind of fuel upgrades would be needed. I was thinking some roller rockers and valve components would be nice to push out my rpm range too.

450ftlbs is great with those mods.

Wow 450 TQ with just those mods? That seems high. I know you've got the LS3, but I've seen L99 dynos posted on the forum that aren't even at 400, and that's with LTs.

well I dropped about 2" in wheel height so i think that helps me spin up those lightweight wheels. But thats the only explanation I got. I was rather impressed with the torque too. although its trashed my drivetrain a couple of times.

Very nice numbers.
I don't know much about Dyno Dynamics numbers -as compared to Dyno Jet or Mustang Dyno.

Also, any idea if your numbers are SAE or STD or uncorrected?

Well, whatever it is, that's pretty sweet. I pulled around 344 HP and TQ with mine. I bet if I added LTs, I'd still only dyno 370-ish.

My mechanic says the dyno is corrected. From what ive read the dyno dynamics read about 12% low. that dyno is corrected by 10%. which would means my number might actually be higher. All i know it was taken at sea level with pump gas haha

You won't gain hp or tq with roller rockers, although a good set of pushrod is never a bad idea but you won't gain hp by getting them just peace of mind. As far as "pushing" your rpms out it won't matter because your hp is peaking at 5500 so it's pointless to go Past 6k ( you see your hp n tq diving on the graph?)

Cam that biach and you'll be close.

yes ive bent both the driveshaft and two axels. I like the pacesetters. i got the armor coated set and they still look brand new and sound great. and as for the roller rockers and rods id do that with the cam. and i guess some headwork or new heads
