This sounds odd to me.....I didn't take a hit when I installed my K&N CAI, nor did I notice any decrease in performance. I did notice what seemed like a little better throtle response, and a 'throaty-er" exhaust note, but admitedly didn't do any scientific testing either so maybe it was just me. Too bad if yours is really having a negative impact as I hear the TruFlow's are a nice (and expensive) setup...

 

Yes I did reset the pcm after I put the trueflow on, andput about 1500 miles on the truck with the trueflow. Now maybe I did not reset it right, so if anybody knows how to on a 06 please let me know.

 

notice that the W.A.G.'ers
keep wanting you to do
'pcm learning' tweaks that they themselves don't understand
and then urge you to keep re-checking the MPG
in order to get a CAI to show an MPG improvement?

The key idea here
is that if you keep doing worthless stuff
and then re-checking the MPG of the next tank of gasoline
eventually,
just by random variation
one of the MPG's will be slightly higher
and they will proclaim
that you have found the improvement
and that you didn't find it before
because 'ya did something wrong'

If you call the helpline of the CAI manufacturer
they will lead you down this same dark trail of excuses and deceptions.

What is the truth?

The truth is that if you do a careful & time proven test
the CAI will show no MPG improvement at all.

In the test described below
Goodyear proved that their tires do improve MPG.
Repeat a similar test with a CAI and it will show no improvement.

The right way to do it
Goodyear goes by the book with Fuel Max test
When Goodyear introduced its new Unisteel tires with Fuel Max technology last year, and claimed that they were more fuel-efficient than its older designs, the company invited the press to come to its San Angelo Proving Grounds in Texas and observe an SAE/TMC Type II fuel consumption test, pitting old against new.

In this case, two identical tractor-trailers — a control rig and a test rig with the same powertrain, mileage, horsepower, GCW, tires, pressure, etc. — were fitted with removable, portable fuel tanks, which were weighed before and after identical runs of at least 28 miles at the exact same highway speed. Fuel consumption was measured by tank weight, and the two rigs were compared as a baseline. Three runs, which must produce results within 2 percent of each other, were made. In this case, the two rigs’ fuel consumption figures were consistently within 1 percent of each other.

Next, the test was repeated, with the control rig unchanged, and the test truck fitted with the component to be tested — in this case, the new tires. Over the course of three runs, with results within 2 percent of each other, the test truck had consumed about 7.5 percent less fuel per run.

Claim made, point proved, case closed.
===
note that you don't have to use the special fuel tanks,
you can do like the Mythbusters TV show
and pump out the remaining fuel from the stock tanks
at the end of the test to measure exactly what was used.

Don't fall for the CAI scam
when there are so many modifications
that do improve both MPG and acceleration.

Notice that the newly redesigned 2009 5.7 Hemi
and the 2008 Toyota iForce 5.7 V8
don't have CAI's ?

 

I also have an 06 and to reset mine - Pull fuse #31, get into truck, close door and put on seatbelt, turn the key to the run position and wait for all 3 chimes (this takes about 2 min.) also truck will not start without the fuse, once chimes stop, pull the key and replace the fuse and you should be good to go. Worked for me, good luck

 

well everyone remember my golden rule... ignore hankL.... the trueflow should be a better performing setup and it was for me... any mpg gains were minimal... however the intake was overall better...

 

I dont know much about true flow but i do know this.....i installed my 57 series....and because of the huge change in air volume it clogged up my throttle body with residue.....not sure if true flow replaces the resonator.....but you might just wanna clean out the throttle body.....give her a shot either way ull gain mpg just because ur tb is clean....i do mine 2 timesper oil change......

 

where in the **** have you been man lol

 

Nice to see you back TD!

 

You still alive, kid? I thought you went riding that new 4 wheeler without a helmet and killed yourself. Then I remembered how thick your skull is and figured you were still with us...

I clean my TB once a year and it ALWAYS is in need of it by then. I did not however notice that it was any dirtier after the CAI went in, about the same. Last time I cleaned it in October, I decided to get the K&N filter charger for over the filter (very minimal loss of air intake but catches a lot of the dust & stuff from off roading before it hits the filter). I'm anxious to see how the TB looks next time I clean it...

 

^^^ That's because the TB mainly gets dirty from the EGR...which doesn't go through the stock setup or CAI.
