Default Disappointing dyno numbers

So I have an 08 4.7 Flex fule. I have done research on all the best motor mods available for the 4.7 but I haven't seen any real dyno numbers after all the mods.
First I did the superchips flashpaq with the 93 performance tune.
Then went to the exhaust shop and put a magnaflow 18 stainless 3" in 3" single out.
Then I did the DIY intake. (it's actually kinda cool) I'll post a pic.
Then I put on the moes performance TB.
Really after that there isn't much more. Unless you get into custom turbos, headers, or other non bolt on parts.

So that being said this is what just under 1000 dollars gets you.
HP 235
TQ 267

I did not get a base line with the truck stock, so don't know how much gained. I feel disappointed
what do yall think?

That's pretty strong. My hemi dynoed 258 rwhp stock. If you want to have some fun, put a 100 shot of nitrous on her and get her to the track. You have about 315 flywheel hp.

That's pretty stout
You put down more torque then my 13 did.
I out horsepowered you,but that's not the important number.
Torque is what counts,as horsepower is just a mathematical equation of Torque and RPM,and is only a number on paper
What make of dyno did you run it on.
A Mustang's numbers are usually lower then a Dyno-Jet's numbers.
I wouldn't be disappointed in those numbers out of a 4.7

Mines been on both a Dyno-Jet and a Mustang dyno,but was tuned on the Mustang.
This is my thread on my 13.

Well I missed some other factors when I made that post. I do run a heavy wheel and tire. It's a 305/40/22. And it was a cool, humid day in fact it was raining. not sure what type of dyno was used.
