How does your truck drive in 4 low with the tunes? For me, my truck is hard to control the throttle when I need to use 4 low. I found this out when I was trying to back a trailer in my in-laws yard. I was using low range because I didn't want to mess up their yard. When I put my truck in reverse and lightly pushed on the accelerator the truck leaped back on me and it was like I had floored it, but I didn't. I did this again after I got the trailer unhooked to see how it shifts and it's crazy... I know it's geared low and shifts quicker but I don't feel like I have any control on the pedal with the tunes. With out the tunes it drives a lot better in low range.

Is this normal? If so 4 low is useless with tunes

 

Using 4low to NOT mess up the yard ??? Thats a little backwards. 4lo gives you more bite, allowing tires to dig in a "grab" the ground. If your on grass, this gives it a chance to grab the ground and tear it up.

Other then that, sounds like 4lo is working just the way it should. You are using the gearing in your t-case to multiply your torque. By goin to 4 low, you now have more "power" and more "neck breaking potential" . I barely give it any gas in 4lo, and my truck will do the same.

 

In 4-Lo with the Troyer Tunes the truck reacts crazy fast and power is instant. Its complete overkill unless i really need to spin them.

 

Tell me if I'm wrong... but I thought 4 low was for maximum traction. I always used it before when I was driving their yard with no problem, with out these tunes of course.


The throttle in my truck is a lot more sensitive with a tuner. Do you have a tuner in yours? When I was trying to back up the trailer in their yard I pushed very slightly on the gas pedal and the truck was flying. So much that I had to slam on the brakes as fast as I gave it the gas. I hardly gave it any throttle at all that's why I'm confused... this is not my first or second 4x4 and not the first truck that I've tuned either. I don't remember it being as sensitive when I was using an Edge or the Hypertech. I also had a Hypertech in my 02 F150 and it wasn't like this either. Just doen't seem right to me
I'm not liken this about these tunes. Can anything be done to help? Since I have the 3.5" intake I'm not thinking I can return the stock programming without reinstalling the stock intake.

 

Well personally, i found that the truck isnt as jumpy off the line with Troyer's tunes as it was with the Edge. But i also dont drive fast, i push the throttle very soft on take off.

Because of the gearing in 4-lo and the power of a tuned 5.4, it just takes off when you hit the gas.

You are correct, if you want stock tuning then you need the stock intake. Otherwise that 3.5" AF1 will lean out your truck badly. Maybe try using 4hi for higher gearing?

 

If your not wanting to tear up their yard I would be using 2Hi or 4Hi if you need a little more traction.

Like MercedesTech said, in 4Lo, with all torque multiplication, the power your pushing, and these trucks having a somewhat touchy pedal even before they are tuned (even more so after a tune), I wouldnt expect anything less when you put yours in 4low.

Low gearing in low, bigger power, and it looks like you have stock sized tires?? It SHOULD jump off the line in Low.

 

then you are using 4-Low at the wrong time

exactly


4 lo is for high torque situations, if it's too much then use 4 hi ir let it idle in 4lo, when I use 4 Low it's only when I'm climbing or tuggin something way too heavy

 

I understand what your saying, it's just that I liked being able to use 4 low so I don 't have to rev the engine to maneuver the truck around the yard. I did try taking my foot off the brake without giving it any gas but the angle of the hill I was on didn't allow it to move. That's when I tried to finesse the pedal a little to back the truck up, it still took off crazy, like I floored it.

I also have a steep hill in my yard that I like to back up every now and then... it sucks now because I really liked being able to walk up it slowly without feeling like I'm gonna blow my engine up.


In this situation, I really like the way it was before the tunes

 

maybe 4lo and instead of drive put it in 1???
just a thought?

 

4low factory has the throttle remapped to prevent that jumpy feel. I guess troyers tuning does not allow for that in his tunes so it is the same between 2h and 4low

 

Interesting, maybe why I never noticed it with the other tuners. If this is correct I wonder if something can be adjusted to correct this.
