I keep hearing how the computer learns as it goes, and adjusts accordingly to your driving habits. Does this mean the faster you drive, and the more you floor it, will equate to higher performance? My truck is very sluggish off the line and through the gears. I don’t floor it often, but when I do, I want a more positive response than what I have now.

I am waiting for the new version of the Micro Tuner the “CAN Flasher” to become available. If the PCM were re-flashed, would the power be there, on demand, even if I didn’t drive it hard very often? Would the “CAN Flasher” do the trick?

 

Hi jp,

Adaptive strategy can reduce power with conservative driving, but not by a lot - so just drive the vehicle normally. This is why some guys, when they take their daily driver to the drag strip, will disconnect the battery for a few minutes to "clear" out the PCM & adaptive strategy adjustments, as they will sometimes pick up a couple of tenths of ET that way - but the same thing will happen just by making a few full-throttle runs. It comes back as quickly as it goes away, and we're only talking about a few percent power-wise, so it's not a big deal - nothing to worry about.

the "power is going to be there" no matter how you drive the vehicle, but it may be say, 97% instead of 100% if it's driven gently most of the time - that comes right back with a few full-throttle bursts over a couple of drive cycles, so it's really nothing to be concerned about.

 

Thanks for that information Mike. Now I need the New Micro Tuner to get rid of the sluggishness. I realize it’s a heavy truck and I’m only going to get so much out of it, but it’s a real dog off the line right now.

 

Hi jp,

Don't feel bad, all us 2004 owners have that same problem!

We can cure that for you - our 2004 F-150 is a 6200 lb. pig - a 4x4 SuperCrew Lariat, and it couldn't even *chirp* a tire off the line at full-throttle when it was bone-stock. But now it will *fry* the tires coming off the line, and put a hurting on any HEMI. We currently have our tuning, intake, exhaust, pulleys & ignition upgrade installed - and it's responded with very nice mpg gains, and a much stronger truck that is much more fun to drive.

We can very easily kick up the performance of that truck even before you get the tuning - if you want. Just give us a call for all the details, and in the meantime, hang in there & enjoy that beautiful new truck!
