Just thought you guys might like to see this power datalog that I did this morning. It's done on my *pure stock* 2006 FX4 w/600miles on it.
This weekend I'll be doing a K&N kit install. I wanted to do a before and after data log of power gained with it. I've done this with my autotap on other Ford products and each times it's been very accurate.
In the linked excell file you can see that I'm down on power as compaired to Fords advertised "207HP & 238 ft lbs TQ". And this is especially true considering the DA (density altitude) of this mornings air. (-1468.4 below sea level) Keep in mind here that these numbers are measured as power is applied into the torque convertor. *not the rear wheels* like as is typical of a chassie dyno.
Reasons for power being low:
I'll investigate the throttle cable thing to make sure that's not limiting me.
I also wonder if there is some sort of break in tune that's limiting power? (the timing seems very low to me)
Maybe the motor and tranny just simply are not broke in enough yet?
Oh and for what it's worth this truck seemed to pull just as strong as the 07s I test drove. So I don't think I'm out of whack with this particular truck.
Anyway.. below is a link to the excell file. And later this weekend I'll make jpeg images of the before and after power gains so those of you w/o excell (or open office.org) can see the gains.
Make sure to scroll down to see the graphs & the dip at about 3100rpms is the torque convertor locking up
