Pretty close to what I made before but had pulley and ported t/b with a 224/230 comp cam. Ended up with 404whp/380tq corrected. How much were you expecting?

Everyone including my tuner (xp in okc) said i should be 410-425. I was expecting at least 400 but hey You win some you lose some i guess. Plus i found out i have some bad valve seals thats probably robbing me of a little power. Going to be replacing those this weekend
Im running xs headers i think there 1 7/8 but im not a 100% i got them for really cheap on here about a year I plan on porting the heads and my intake and throttle body also getting an underdrive pulley, maybe throwing a 100 shot at her
I would love to get a fast but there just so damn expensive also my tuner said my ls6 intake was good to about 525rwhp. Just out of couriosity is there any other intake tb cobos out there that are less expensive then a fast but flow better then the ls6

Dyno numbers don't really mean a lot (keep telling yourself that)... The real number is running it down the track and seeing where your ET & MPH are.
the cam is on the small side and the heads are probably restricting you but hey...run it and see if you want to go faster - enjoy it!

I know dyno numbers are not very reliable, but i still want to get the car to the 400+ mark on the curr set up. But ultimately i want to be in the 11's this season. I will be taking it to the teack this weekend. Excited bc i also replaced the very bald tires and c6 wheels for 18's all the way around with nitto 555. i ran a best of 13.09 my last time at the track. So hoping for a huge improvement maybe low 12's with fixing thevalve seal problem, tune and tires.

How does it feel? I have a 03 m6' getting tuned next week with the same cam, vararam, lg long tubes with cats. 400 to the wheels will be great for bragging, but I really want a 11 second quarter mile.

We did some testing on the dyno when I swapped out the ls6 intake for a fast 92. It picked up almost 18 rwhp from that alone. I'd say the cam and possibly injectors could be holding you back. I made 417 with stock heads and these mods:
BTR Stage 3 Cam
BTR Titanium retainers/springs
Blackwing Filter
LS2 TB
FAST 92 Intake
FAST 39lb/hr injectors
Kooks LT's and Xpipe
Borla Stingers
FireCore50 wires

From comparing graphs it looks like you have more torque earlier than I do. I can certainly feel a loss of torque when loafing on the highway in 5th and 6th. Though the power running through the gears is great.
Wish I would have dumped the stock axle back, but was worried about noise. Thinking that will be my next purchase (corsa extremes).
I don't break the 350 mark for torque until 4.5K.

Dynos can read different and are just a tuning tool. You may try another to see if it gives you a higher reading, though that doesn't mean the car is any faster. An UDP would have put you real close to 400rwhp, curious what headers you are running as well as wheels/tires and clutch. Lighter rotating weight from them as well as a lighter clutch will mean less parasitic loss to the wheels, hope that helps.
