Got my truck dynoed, 5.4 v8 xlt, its basically stalk except a cold air intake it has some 18" rims and about 30" tires, well the numbers from the dyno were alittle disappointing and almost seem to low to b right so tell me if these numbers sound right? my best run was 185 HP and 212 torque.... seems a little low to me??

 

How many miles?

 

This and what year? What maintenance that you know of has been done? Also what conditions did you test the truck under? You give a little but you want a lot get what I mean?

 

An 06 71000 miles and southern Cali conditions...

 

Sounds very possible. The trucks made 300 hp at the crank. 13% lose for drag and what not equals about 210 at the wheels. 25 hp lose over 5 years is totally possible. 5 hp a year. It sucks but its the truth. Top Gear has done tests with cars that have lost over 100 hp throughout its life.

 

Damn... is there any way (some sort of engine cleaning I can get) to get that power back

 

Uhh I don't really agree with that statement. Horsepower loss over an engine's life is possible, but the pistons, cylinders, rings, and everything else doesn't start truly wearing down until at least after 100k if driven normally. Do you have any CELs, and have you don't any maintenance on the truck? This truck still has a lot of life to it, there is no reason it should be putting out those numbers even considering drivetrain parasitic loss.

 

So they should b better?

 

What elevation are you at? Air may be thin.
