Guess the Dyno #'s on this Tuned F150
Found this from Mike:

The 5.4 3V motors, if actually allowed to turn enough rpms to hit their power peak at the rear wheels, generally make their 300 HP rating from what we've seen - they are not significantly under or over-rated, on average."
So I *probably* gained 37 HP which doesn't sound good, but 257 at the rw isn't too bad overall for a 3.25" AF1 and maggie exhaust. I can certainly feel the power gains when driving. I also think there is more there since I'm running really rich.

Well I may be wrong but once my fuel curve is fixed I should also see an improvement.
I'm big time lean (over 13) at low RPMs. Then it dives down to big time rich (off the charts rich) at higher RPMs.

his HP went from 7200 rpm and 318 rwhp to 6700 and 337 rwhp just from fuel. i watched it with my own eyes.

So all the mods netted a max of 10-21hp.
Just FYI.
Curious to see what the $$ to HP-gained ratio would be?
Has anyone chassis dyno’ed a stock motor?
