Default Opinion on dyno results

Sup guys wanted to get some opinions on if the dyno results are where they should be. Truck is 2005 Silverado 5.3 has btr stage 2 truck cam, LT headers ,3 in y pipe and high flow cats . Everything else is stock. Truck made 318 hp and 315 tq. I know the truck is over 10 yrs old but was expecting a bit more ....this make sense?

There are so many variables. What kind of dyno? IS it a 4x4? What gear did you dyno in?

that being said... it doesn't sound bad to me at all. Essentially 100HP from a mild cam, headers, and a tune.

Gears will also make the dyno read different. It’ll make a nice difference but won’t necessarily translate at the dyno very well.

numbers sound right, the 706/853 heads in stock form arent the best for peak numbers....as mentioned above the truck was prob 230ish WHP stock, some 3.73s or 4.10s will make it feel like a whole new truck...
