Looks about a 30HP increase from just a cam. When you get headers and a FWI I would expect closer to 380 then. How does it run compared to before?

Did you install it yourself?
no, a shop did.

it drives pretty good, you can definatly feel the difference.
people were saying that it will need a converter, but its really not that bad.

Did you have it tuned after the cam install? Also was this a loaded dyno?

Those numbers seem really low, but you dont have any exhaust, so I'd be hopeful in seeing you crack 400whp with some.

Man you need to have some one look at your tune. My truck made 350 on the dyno and all I have is no kitty's and a CAI. Something is wrong. You should be pushing 375 easy.
Obviously you ran on a generous dyno. Because most stock tbss trucks dyno 300-320 (most around 300) stock depending upon awd or rwd.
A dyno is just a tool to see how your mods perform anyway (before and after). It's not a scientific method of saying "my truck has more power than yours". Especially if you're running on 2 different types of dynamometers, load bearing or non.

Very helpful... But real world numbers should honestly be on tha track.... There are 500hp trucks running 10s and 1200plus ones barely in low tens... Hell I seen a 650hp tahoe barely go 12.5s. All in all have perfect race weather and track settings go.out run ur best and come out with a kick asd time... and brag bout that... Not bitchin or talkin shit there is just so many numbers floating around and so much drivetrain loss that u can never truely tell... U could have ten stock tbss line up theyll all pull different!

the truck's dyno numbers are alright,

the was a lot of timing pulled because of the factory manifolds.
was 110 degrees in the shop.
te truck is completely stock except a cam.
once i get the headers and intake, the numbers should be closer to 400,

and very true to what lt1z said,
my other car dyno'd 30+ whp more on a shops dyno than it did at anothers.
numbers really mean nothing to an extent,

plus the truck has got 110k
